The above is Part Seven from a lec­ture given by Attor­ney Justin J. McShane before the North Car­olina Advo­cates for Jus­tice “Advanced DWI Sem­i­nar”. This sem­i­nar hap­pened on Feb­ru­ary 26, 2010. It was orga­nized and hosted by John K. Fan­ney, Esquire of Fan­ney & Jack­son, P.C. The fol­low­ing is a tran­script of this video:

One of the ques­tions that gets asked some­times is “Why can’t the machine test whole blood?” The rea­son why it can’t test whole blood, I’ll explain here in a minute, it’s the way it’s set up. When you do hos­pi­tal blood tests it’s an enzy­matic method involv­ing a reagent. It’s col­ori­met­ric and spec­trom­e­try based upon Beer’s law.  And what does that mean? The most impor­tant thing to take away is this slide up here.

It is not selec­tive and it’s not spe­cific.  What I mean by that is it is not some­thing much dif­fer­ent than this right here. This is not selec­tive. It’s not spe­cific. It’s so bad that if you had dark choco­late, I’m from nearby Her­shey — I didn’t bring down a Her­shey bar this time.  If you put a Her­shey bar in this thing, you put crushed up Tylenol PM inside of here, you put in a lot of things it can put in a false pos­i­tive. Same thing that hap­pens here.

And the biggest source of inter­fer­ence is by what’s called lac­tate and we are going to show you why lac­tate is what you are look­ing for. Ringer’s lac­tate is an IV solu­tion that’s given dur­ing trauma or when they think some­one is going to go into shock. If you have ever seen any of the ER shows it’s sit­ting there and they are giv­ing it in the person’s arm, and they are car­ry­ing through and every­thing like that. It’s called fluid resus­ci­ta­tion and what it does is it’s pump­ing through a bunch of elec­trolytes and lac­tate in hopes that you don’t go into shock and not die of your injuries but die of shock. It is almost uni­ver­sally used in every sin­gle acci­dent case that is out there and any sort of injury that is out there.  But it gets bet­ter than that. It gets infused, and what I mean by that is they often­times put them in both arms and they set it there, and they squeeze the bags in order to get it into the blood as quickly as pos­si­ble. That is how you get the admin­is­tra­tion of lactate.

So what you need to do is when you have an acci­dent case that involves an emer­gency room and enzy­matic assay test, hos­pi­tal blood test­ing (and that is how they are try­ing to get your client) what you need to do is you need to take a look at the admis­sion charts that go in there because they should be record­ing what’s in each person’s arm and body as they come in.  But more impor­tantly the most use­ful that I find is sub­poe­naing the ambu­lance crew and they have their own doc­u­men­ta­tion that is out there, and also their replace­ments so you can know specif­i­cally.  Because as soon as they are done using their Lac­tated Ringers they have to order a new one. That is the type of thing that you should be tak­ing a look at.

Two other things, what else releases lac­tate? Trauma. Soft tis­sue trauma. Heart tis­sue trauma.  If you are in a car acci­dent and you break your leg, espe­cially your femur then it will release lac­tate. If you are beat up, if it is soft tis­sue dam­age inside, like the steer­ing wheel hits your ribs and cracks your ribs and hurts, you that can release lac­tate. Remem­ber the words TCA? TCA is where they got the depro­teiniz­ing agent.  Believe it or not is the very process of adding TCA, you release lac­tate.  So think about that. That means that every sin­gle time that you are using TCA you are going to be jack­ing up your BAC result.  Tell me how fair that is. It is impos­si­ble to tell what is alco­hol and what is lac­tate and I will show you why. The con­clu­sion for hos­pi­tal blood is it is not selec­tive. It’s not spe­cific.  It’s cer­tainly not foren­sic and it belongs nowhere inside a court­room whatsoever.

We are all at least famil­iar with the way that a breath test machine works and an infrared breath test machine in par­tic­u­lar, and that is based upon IR or infrared, and that is based upon Beer’s Law, the prin­ci­pal of Beer’s Law. You have an infrared light source, and the way that it is sup­posed to do the mea­sure­ment accord­ing to Beer’s Law is as it goes through the sam­ple cham­ber. If there is noth­ing inter­fer­ing with it, when it hits the detec­tor it should be at the same exact inten­sity.  So the arrow does not become smaller, it remains the same. As it is going through if there is noth­ing there to inter­fere with it the same amount of energy hits the detec­tor. We all know that because you guys are a great breath-testing state. If you put in a mol­e­cule of inter­est, let’s say alco­hol, inside that sam­ple cham­ber it inter­feres with it and it shakes it up kind of, it’s asym­met­ric; and then the amount that it starts out is decreased because it is absorbed by that par­tic­u­lar mol­e­cule as it hits the detec­tor. That is how you know how much alco­hol, what they say that the prin­ci­ple of alco­hol breath test­ing is based upon.

No dif­fer­ent in hos­pi­tal blood test­ing.  In hos­pi­tal blood test­ing it’s based upon again that uptake that’s involved. This is the spec­tra of ethanol. This is the wave­lengths of, if you were to take it out over the entire spec­trum as far as what it looks like. As we have prob­a­bly been exposed to before, and I only use it to illus­trate how bad hos­pi­tal blood test­ing is, with an Intox­i­lyzer 5000 or most of the other mod­els that are out there it is a three fil­ter process or a five fil­ter process, mean­ing that it is designed to take a look at cer­tain wave­lengths at cer­tain points in time that may not be unique to alco­hol.  In fact it is designed not to look for ones that are unique to alco­hol as opposed to any­thing else that comes out there. The most impor­tant thing is that it is a three to five fil­ter process. It is look­ing at three areas or five areas. Hos­pi­tal blood test­ing looks at one. One. It is less spe­cific. It is junkier because it only looks at that one wave­length. It only looks at one of the 340 wave­lengths that are there.

 

The above is Part Six from a lec­ture given by Attor­ney Justin J. McShane before the North Car­olina Advo­cates for Jus­tice “Advanced DWI Sem­i­nar”. This sem­i­nar hap­pened on Feb­ru­ary 26, 2010. It was orga­nized and hosted by John K. Fan­ney, Esquire of Fan­ney & Jack­son, P.C. The fol­low­ing is a tran­script of this video:

This is an exam­ple from a case that we just went to trial on. When you blow it up, this is the infor­ma­tion you get from the Lab­o­ra­tory Infor­ma­tion Sys­tem. It is a one sheet con­clu­sion. What the one sheet con­clu­sion is when you blow it up, just says .127 abnor­mal results for alco­hol, but if you notice it says ‘whole blood’. It is not an expres­sion of whole blood. Unfor­tu­nately for your client, most of the time you sit there and go “Oh my God, he’s screwed,” right? But that is only because you take a look at that one sheet of paper. Let me ask you a ques­tion. If you got a police report that sim­ply said, your client was drunk. Would you just say “I give up,” “I’m done”? Why do we do that when we get a result? Why do we say, “We got one piece of paper that says .127 whole blood, well geez, I’m done”?

You would not accept that when a police offi­cer tries that busi­ness. Don’t accept it when a lab tries that busi­ness. The devil is in the details. You know the process. What comes out of the machine is not a whole blood result but they are report­ing it as a whole blood result. The rea­son you can catch them is, not by just know­ing the SOP that we just went through, but you can also take a look at the details. This is the instru­ment ticket. This is what it actu­ally prints out or some­thing like this depend­ing on your machine. We are going to blow it up and take a look at it. This is from a dif­fer­ent case but this is one of the best illus­tra­tions that are out there. Some mood music. It’s tran­quil. You get the evi­dence ticket that comes out of the machine and you can see very plainly, it says serum. That is why you have to go back and not just accept the police offi­cer say­ing your guy is drunk. Don’t accept the ana­lyst com­ing in and say­ing your guy is a .127. Peel back the onion, go get the tick­ets and you can see right in there that it is a serum.

Yes?

Male: Just a quick ques­tion. When it cen­trifuges and the lighter stuff comes to the top then is the alco­hol one of the lighter things? Isn’t that basi­cally what is going on?

Yes. Of course if you think about it, it makes a lot of sense. We know in our daily liv­ing what alco­hol is like. Blood is a lot heav­ier than that because of all the junk in it. You are right. It does sep­a­rate alco­hol to the top, which is a good point.

You can catch them with their own stuff inside the lab when you peel back the onion but it gets more com­pli­cated than that. This is what’s called the cal­i­bra­tion curve. It is impor­tant for you to know what it means. The cal­i­bra­tion curve is the way the ana­lyt­i­cal device is shown to be within tol­er­ant range. That it is accu­rate and pre­cise. You don’t have to be a rocket sci­en­tist to under­stand a lot of this stuff. It is low hang­ing fruit that any­one can under­stand. They are try­ing to run through the machine to make sure it is accu­rate and pre­cise and they are com­par­ing known stan­dards and see­ing what the machine does with that. The rea­son it is low hang­ing fruit is because it will tell you often times the prob­lems that go along with it.

Blow­ing this up, we take a look at it. You can right here, it is in your mate­ri­als, and it says cal­i­bra­tion sta­tus not accepted. Who in this room would think that means the thing is okay? You do not have to be an ana­lyt­i­cal chemist with a PhD to real­ize that if some­thing isn’t cal­i­brated it isn’t work­ing right. It is not good. Then if you take a look a lit­tle fur­ther down, I don’t know what this means, but I found out what it meant. It has neg­a­tive num­bers. If you are mea­sur­ing some­thing, espe­cially some­thing like alco­hol, think about this, zero means noth­ing. How can you have a neg­a­tive value, is it really, really not there? You have to really think about these things. It even says error assay range but because it’s good enough for gov­ern­ment work what does the ana­lyst do? The ana­lyst says A-okay.

Yes?

Male: What you have on the screen, is that a lab report? And, how would we get that?

You are going to request the cal­i­bra­tion curve. One of the things I will do is email my super sub­poena that I have in dis­cov­ery request and it will be in the liege of doc­u­ments you have there. Par­tic­u­larly, how you are going to get it is through sub­poena. Ask­ing for it and insist­ing that you get it using these types of things as exam­ples of what can go wrong. Like I said, it is low hang­ing fruit.

In this par­tic­u­lar case, we have five years’ worth of data on this par­tic­u­lar machine. From the date of this, which was July 30, 2007 and they cal­i­brate it every sixty days, because he forced an agree­ment and said it was ok. Every­one for that sixty days was get­ting screwed. That is a lot of peo­ple. The next time they came out, they did a new cal­i­bra­tion curve that is there and again, you don’t need to be a rocket sci­en­tist. On this one, the low range value says it was out­side the assay range. In this par­tic­u­lar one, again what you have is the high val­ues. They couldn’t get it right low. The next time, they couldn’t get t right high. They just couldn’t get it right and they couldn’t fig­ure it out so they just kept on test­ing peo­ple. You bring this in front of juries. You bring it in front of judges.

Judges will under­stand that because it is low hang­ing fruit and it says stuff like not accepted. Not accepted, that is pretty pow­er­ful lan­guage. It is some­thing you really need to take a look at and it doesn’t require rocket sci­ence. You just have to be exposed to it by com­ing to these great sem­i­nars and know­ing that it is out there instead of just accept­ing one piece of paper, don’t accept the traf­fic cop’s say­ing, “You’re guilty.” Don’t accept the lab sci­en­tist try­ing to do that same jazz. Make sure it is right. Be their exter­nal val­i­da­tion check. Then you get beau­ti­ful stuff like this. North­ern Penn­syl­va­nia, extremely rural, I asked for the dis­cov­ery on this par­tic­u­lar case, I am not going to say what county it is in — I have redacted a lit­tle bit of it because it is going to be lit­i­gated. It is going to be like a Pearl Har­bor moment in their life. They are not going to see this coming.

When I asked for it, this ana­lyst, basi­cally what it says here in the sam­ple is, plasma and they put on their ticket, “When com­plet­ing whole blood alco­hol put a line through ‘plasma sam­ple’ and write in whole blood fil­trate on all print­outs.” You can’t make that stuff up. That hap­pens out there. It prob­a­bly hap­pens in your state. And it is not because this per­son is try­ing to be a crook. It is because the machines are run by oper­a­tors who are not hard-core sci­en­tists. Gen­er­ally they are peo­ple who have an Associate’s degree or were nurses and they wanted to work in the lab because they got sick of work­ing with peo­ple so they got re-tasked, reas­signed. It is not like they are try­ing to screw your clients. They don’t under­stand the dis­tinc­tion and how impor­tant it is but you can under­stand it.

It is not really impor­tant that you under­stand all the jibber-jab that is inside the machine. You just have to under­stand the process. You have to under­stand that there is infor­ma­tion out there that you should be get­ting in order to make things right. Again, whether or not you know the par­tic­u­lar sci­en­tific break down of the machine is not as impor­tant as under­stand­ing the processes.

 

The above is Part Five from a lec­ture given by Attor­ney Justin J. McShane before the North Car­olina Advo­cates for Jus­tice “Advanced DWI Sem­i­nar”. This sem­i­nar hap­pened on Feb­ru­ary 26, 2010. It was orga­nized and hosted by John K. Fan­ney, Esquire of Fan­ney & Jack­son, P.C. The fol­low­ing is a tran­script of this video:

So to really under­stand what we are talk­ing about here, you have to under­stand a lit­tle bit of sci­ence. What I mean by that is the dis­tinc­tion that is up here between whole blood, plasma blood, and serum blood. It is visu­ally dif­fer­ent. Over here is whole blood.  That means basi­cally what came out of your arm and what got into the tube. Two other types of blood are plasma blood and serum blood. This is what they are doing a test­ing of over in the lab for hos­pi­tal blood test­ing. They are visu­ally dif­fer­ent. Serum blood test­ing has a clot that is right there with the sep­a­ra­tion on the top. You can read what the com­po­nents are as far as the dif­fer­ence between plasma and serum. But the most impor­tant thing to rec­og­nize is, like Sesame Street: “One of things is not like the oth­ers, one of these things…” This is whole blood.  It is visu­ally dif­fer­ent from plasma, visu­ally dif­fer­ent from serum blood.

I’m going to tell you that when they make the con­ver­sion between plasma and serum blood back into whole blood, because whole blood is what statutes are based upon.  If you are .08 state, which all states are — my state has dif­fer­ent tiers, .08, .10. .16 — that con­ver­sion back between plasma blood and serum blood, if you believe it’s pos­si­ble to do, results some­where in the mag­ni­tude of a 59% over­state­ment. That means what comes out of their machines at the end of their process is about 59 % too much. It is 59% over­stated and I am going to show you why. That’s because you are not test­ing the whole blood.  You are remov­ing things out of it. What is impor­tant is for you to know the process so you can rec­og­nize when it is not a whole blood test. Because whole blood is what a con­vic­tion is based upon.  Mean­ing grams per­cent inside as an expres­sion of weight, of vol­u­met­ric weight, of whole blood as opposed to serum or plasma. If you have a plasma result or you have a serum result, it shouldn’t be reported in court as a whole blood result, but they do it all the time and I will show you how they do that.

This is what hap­pens with the lab sci­en­tists. The lab sci­en­tist gets a nice, pretty, gray tube top  This is a pipette.  This is a solu­tion and the solu­tion has an acronym that’s called TCA (trichloroacetic acid).  What that is designed to do, it’s called a depro­teiniz­ing agent. Inside of our blood we have pro­teins, and what needs to be removed in order for these types of machines to work are the pro­teins because it inter­feres with get­ting a result at the end of the day. What hap­pens is they take the pipette.  They load it up with TCA and then they put it in a tube. That is the first step that’s there.  What they do after that, they take that, they bring it over to what’s called a vor­texer. What a vor­texer does is it mixes up the TCA that’s inside of there. That takes the TCA, just like oil and water, and mixes it up so that it is homoge­nous, mean­ing it’s all the same type of thing mixed in there. It forms a pel­let at the bot­tom because you are remov­ing the pro­tein. The pro­tein binds, because of TCA and goes to the bot­tom.  You can see a pellet.

Next they take it over to a device called a cen­trifuge. The impor­tant thing to know about the cen­trifuge is that once it goes in there they load up a bunch of sam­ples all at the same time and they spin it at a 450 angle. Has any­one seen the movie Spies Like Us? Remem­ber that scene when they go to the cen­trifuge and the guy’s face is all get­ting smushed back and every­thing like that? That is a cen­trifuge. It is the same thing that hap­pens here. Through the force that goes on when it spins around, what ends up hap­pen­ing is the lighter stuff goes to the top and the heav­ier stuff goes to the bot­tom. It’s pretty sim­ple. It cre­ates a very vis­i­ble, dis­tin­guish­able sep­a­ra­tion that’s there. This is what it looks like when it spins in there. There are vari­ables that go in there. If you don’t spin it the right way then it’s no good.

The whole point is that after it comes out of the cen­trifuge, you can see the sep­a­ra­tion that’s there between the yel­low vis­cous mate­r­ial, the plasma at the top; and at the bot­tom you can see what’s out there. So again, it turns into that dis­tinc­tion between the red blood cells, the heav­ier stuff’s at the bot­tom, the lighter stuff’s at the top.

I bring this all to you so that you can under­stand this next, most fun­da­men­tal step. This is the most impor­tant step and this is how you are going to get them, and you are going to show in this process that it is not a whole blood result. It is the sin­gle biggest way that I know how to win these types of cases. If all you have to do is show that it is not a whole blood result and they don’t have some­one to come in and tes­tify sci­en­tif­i­cally as to their con­ver­sion rate because it is not whole blood.

It comes down to this nice lit­tle dirty secret. It’s cen­trifuged.  It’s sep­a­rated, and what they do is they take the pipette and draw up just…  And it is called aspi­rat­ing the super­nate. If you are read­ing through your SOP’s (Stan­dard Oper­at­ing Pro­ce­dures) of the hos­pi­tals, if you see the word super­nate, you won. You don’t have to know any­thing else — just look for that word “super­nate”. You aspi­rate, which means you draw up the super­nate, which is only this yel­low com­po­nent. You don’t care about the rest. Then what you do after that — it goes over there into your spec­i­men jar, and  then you take the rest of it.  Because you’re only tak­ing the yel­low vis­cous mate­r­ial, not all of it, just a very small por­tion of it, about that much into there.  You take the rest of it and you throw it away. That’s what they do in these labs.

They take the rest of the stuff, mean­ing the red blood cells, mean­ing the fib­rin, mean­ing the pro­teins and they throw it away.  It never makes it to the ana­lyzer. Then in your pipette is only that yel­low vis­cous mate­r­ial. They take it over to an ana­lyzer.  This is a Dade Dimen­sion RXL Max, a highly com­pli­cated machine, at least it looks that way.  But the most impor­tant thing to know is that it is only test­ing, through that reagent process which we’ll go over in a minute, the yel­low vis­cous mate­r­ial that is con­tained inside. So what ends up hap­pen­ing is, and this is an impor­tant dis­tinc­tion right here, is that the only thing that makes it to the machine, out of all the blood, out of your entire blood, is that yel­low part, the plasma part.  So it is not a test on whole blood. It is a test on the yel­low part or the super­nate. That is the most impor­tant thing to take away from here.

But as we will see, there is a big dif­fer­ence between what hap­pens in the clin­i­cal world and the foren­sic world. This is an inter­face that’s called the Lab­o­ra­tory Infor­ma­tion Sys­tem. The Lab­o­ra­tory Infor­ma­tion Sys­tem is a com­puter. This machine prints out lit­tle tick­ets, kind of like a BAC Data­Mas­ter or an Intox­i­lyzer or some­thing like that.  But the Lab­o­ra­tory Infor­ma­tion Sys­tem is an exter­nal thing that doesn’t inte­grate with it. Some­one sits there and puts in the hand input. It’s not con­nected to the machine, and reports the par­tic­u­lar results. That’s what ends up hap­pen­ing, is they only test the yel­low part of it.  And it is most dis­tinctly, as you can see, it’s not whole blood.   It’s not whole blood.

 

The above is Part Four from a lec­ture given by Attor­ney Justin J. McShane before the North Car­olina Advo­cates for Jus­tice “Advanced DWI Sem­i­nar”. This sem­i­nar hap­pened on Feb­ru­ary 26, 2010. It was orga­nized and hosted by John K. Fan­ney, Esquire of Fan­ney & Jack­son, P.C. The fol­low­ing is a tran­script of this video:

Now, this is a micro­scope.  In fact it’s called a stere­omi­cro­scope. Believe it or not in most states it is how they come to this con­clu­sion. That the green leafy sub­stance is in fact marijuana.

Let’s think about that for a minute. How many peo­ple here have ever defended a mar­i­juana case?  I imag­ine most peo­ple, right? You get back the lab report that says one sen­tence, “Hey, it’s mar­i­juana — your guy’s done.” Does any­one have the SOP (Stan­dard Oper­at­ing Pro­ce­dure) to fig­ure out what sort of ana­lyt­i­cal test­ing they are doing in order to deter­mine that it is in fact mar­i­juana to the exclu­sion of all other green leafy sub­stances? Anyone?

Think about this — more than likely what they are doing in your state, even in the state lab, I don’t know if you have local labs around here, what they are doing is stere­omi­croscopy.  What stere­omi­croscopy is, is basi­cally they are tak­ing a look under the micro­scope at a rel­a­tively low power, usu­ally about 20x or 25x, and they are look­ing for char­ac­ter­is­tics that they believe to be con­sis­tent with mar­i­juana and noth­ing else.  And so the bot­tom line of it is, if you think about it is “I have trained eye balls, my eye balls are bet­ter than yours.  And because I take a look at this green leafy sub­stance and specif­i­cally when we zoom in and we take a look at it…”  What they are specif­i­cally look­ing for is called cys­tolithic hairs that react to duquenoid or acid and they cre­ate bubbling.

That is totally sub­jec­tive.  There is a paucity of stud­ies out there if there are any at all that would be able to deter­mine whether or not to the exclu­sion of all other types of plants on the planet Earth that only mar­i­juana, and only mar­i­juana has cys­tolithic hairs that reacts to chem­i­cal process by bub­bling. There is no study out there.  So if your state is doing botanical-based, that’s what it’s called – botanical-based stere­omi­croscopy — that’s a very big prob­lem because it’s sub­jec­tive, it’s not empir­i­cal and so you have to be aware of that.

What’s worse is even in my state, Penn­syl­va­nia, they do what is called polar­ized light microscopy. This one is even fun­nier, and it’s for cocaine. They flu­o­resce it under the micro­scope and if they see twin­kling in this type of fash­ion under that micro­scope it’s got to be cocaine. That’s the busi­ness that is going on out there. We don’t know about it because we’re not exposed to it. You need to expose it in front of a jury and show what it is, it is not sci­ence, it is not foren­sic in nature but it is sub­jec­tive in nature.

There is bet­ter test­ing out there such as GCMS (Gas Chro­matog­ra­phy Mass Spec­trom­e­try) that will sci­en­tif­i­cally get rid of this “I have a great set of eye balls” type of busi­ness that goes on in state labs. So you have to be aware of those issues and types of things that are out there because if you rely upon “my trained set of eye balls, my high-grade, trained set of eye balls,” can any­one tell me just by look­ing, not from your own per­sonal expe­ri­ence; just by look­ing and what you have seen on the inter­net or some­thing like that, which one is mar­i­juana, which one is not mar­i­juana?  Or trick ques­tion — is there mar­i­juana up there?

The rea­son why you can’t do this whole hocus pocus of “I can tell by look­ing at it” type of thing is because you can have a lot of inno­cent things that look anal­o­gous to it.  And these are nice exam­ples because you get the whole leaf, most of the time, if you ever look at the evi­dence it’s not these nice pretty leafs.  It’s usu­ally the bud mate­ri­als and things like that, it’s ground up and every­thing like that, you don’t get the whole leafs.  But the bot­tom line is on the left is the Japan­ese maple leaf, and on the right is our pot leaf.  So you have to not accept when they come in with these botan­i­cal based con­clu­sion, espe­cially when it comes to seeds because of course, at least in my state — I did not do the research in your state — it’s the THC is what makes it ille­gal as opposed to hemp or deac­ti­vated. How you can tell a seed is going to ger­mi­nate in order to pro­duce THC by look­ing at a seed is about the most ridicu­lous thing in the world. That is the most ridicu­lous thing in the world.  So you have to be exposed and you have to know these things in order to be on the look­out for them, and its pat­tern recog­ni­tion which is just gen­er­ally junk.

We’re talk­ing about foren­sic ver­sus non-forensic test­ing and the big dis­tinc­tion there and why is it impor­tant. Non-forensic test­ing is stuff that doesn’t belong in a court­room. Foren­sic test­ing belongs in a court­room only if done prop­erly — pretty big dis­tinc­tion. Non-orensic test­ing is like this type of stuff that we had up here, the col­ori­met­ric related tests that have false pos­i­tives. That does not belong in a courtroom.

I want to talk to you about one that’s near and dear to my heart and now we’re going to start talk­ing about blood test­ing.  It’s hos­pi­tal blood test­ing. I’m on a cru­sade to end enzy­matic assay, or what is called hos­pi­tal blood test­ing in the United States.  For deter­mi­na­tion of a Blood Alco­hol Con­tent.  And I am going to show you why it is so par­tic­u­larly dan­ger­ous in terms of false pos­i­tive rates, its non-selectivity and prob­lems that exist with it.

By way of anal­ogy, there are two ways… I have a daugh­ter. She’s six­teen months old.  She’s gor­geous.  She’s the light of my life, I just absolutely love her.  She runs around, tod­dles around and does all fun things that a six­teen month old does. There are two ways to weigh my daugh­ter.  The first way is I take my daugh­ter, get out the scale, and I put her on the scale and I see what the scale says. That’s called a direct mea­sure. The other way to do it is I weigh 203 lbs; my daugh­ter, because I did the direct mea­sure­ment of the scale, is 23 lbs. The sec­ond way of doing it is I get on the scale with her on it after I know that I am 203 lbs.

Let me restate that a lit­tle bit eas­ier. The first way you can do it is you put out the scale and you put her on it, and it says 23 lbs — direct mea­sure­ment, noth­ing inter­feres.  It’s a direct mass mea­sure that’s there.  You take her off. The sec­ond way of doing it is if I hop on the scale first, I see that I am 203 lbs.  I step off the scale.  I go grab the tod­dler and she’s wig­gling and every­thing like that, then I go step on the scale again and it says 226 lbs. Then what I do is I take the 226 of the both of us, sub­tract the 203 of the known — that is me.  That comes up with 23 lbs.

What ends up hap­pen­ing that sec­ond way, if I do it that sec­ond way, the indi­rect mea­sure way what ends up hap­pen­ing is my wife looks at me like I’m stu­pid and says “Why on Earth did you weigh our daugh­ter that way?  Why didn’t you just put her on a scale?”  And that is pre­cisely what is hap­pen­ing in hos­pi­tal blood cases. They are not mea­sur­ing ETOH or drink­ing alco­hol, They are not mea­sur­ing that at all.  What they are doing is called an indi­rect enzy­matic assay test­ing, and I am going to explain every sin­gle one of those words.  But the rea­son why you have to be aware of it is because in trauma-related cases where you have some­one who is a drink­ing dri­ver or accused of drink­ing and dri­ving shows up in a hos­pi­tal, that is where you’ll see it most of the time.  And then they pull, as part of their med­ical course of treat­ment, dif­fer­ent blood tubes at the end of the day.

What you have to do is you have to think about the envi­ron­ment that it is in. The envi­ron­ment that it’s in is not a foren­sic envi­ron­ment.  It’s not run by sci­en­tists.  It’s run by clin­i­cians — peo­ple who are look­ing to do “stat, imme­di­ately, now” treat some­one with an acute prob­lem. So it’s fast and it’s dirty and you can’t run a GC type of test or Gas Chro­matog­ra­phy type of test because that takes sev­eral hours.  By that point in time the per­son is either dead, treated, or stabilized.

So instead what exists out there is hos­pi­tal blood test­ing because it’s fast. This type of test­ing is also fast but it’s not accu­rate as we saw here.  It is not pre­cise.  It’s not selec­tive and it does not test for mar­i­juana to the exclu­sion of all other things. That is the prob­lem with hos­pi­tal blood test­ing. It’s help­ful in a clin­i­cal envi­ron­ment of an emer­gency room. It’s dis­as­ter in a courtroom.

 

The above is Part Three from a lec­ture given by Attor­ney Justin J. McShane before the North Car­olina Advo­cates for Jus­tice “Advanced DWI Sem­i­nar”. This sem­i­nar hap­pened on Feb­ru­ary 26, 2010. It was orga­nized and hosted by John K. Fan­ney, Esquire of Fan­ney & Jack­son, P.C. The fol­low­ing is a tran­script of this video:

What we’re going to do, because it is early in the morn­ing and I hate early in the morn­ing… But I love my cof­fee. I am going to need some vol­un­teers and I am actu­ally going to pick them because I am usu­ally the per­son in the seat who hates to be both­ered this early in the morn­ing. I am going to pick you, and you look­ing down, try­ing not to be picked. Come on up. What we have here is the most pop­u­lar form of reagent based test­ing that is done on the street. This is called the NIK Pub­lic Safety, the Nar­cotics Iden­ti­fi­ca­tion Sys­tem. Doesn’t it sound really won­der­ful? It is a col­ori­met­ric test; this is what they do when they stop some­one on the side of the road. I am going to ask you to do this. This is just cof­fee from my room. Would you do me a favor? Would you raise your right hand? Repeat after me; I am going to put you under oath. Do you swear to tell the truth, the whole truth and noth­ing but the truth, so help you God?

Female: I do.

Are you, right now under the penalty of per­jury, are you in pos­ses­sion of mar­i­juana? Are you?

Male: I would say that I do not think I am in pos­ses­sion of it.

Alright, lawyer.

Female: Not that I am aware of.

Not that you are aware of, okay. Is it mar­i­juana? Take a look at it. It just came right out of this pack­age, you saw me open it. Is it marijuana?

Female: No.

Male: No.

Alright. What I am going to do here is take this kit, and it is a color based reagent test kit, it is based upon three ampoules and the way that dif­fer­ent things that are there. What we’re going to do is fol­low the exact direc­tions that are there. As you can see, there is noth­ing in here what­so­ever. And I am just going to get some air intro­duced in there, I am going to flap the darn thing over, I am going to fol­low the direc­tions on the thing that’s here. Why don’t you do me a favor. Why don’t read out loud the direc­tions that are right there so that every­one can see that I am doing what I am sup­posed to be doing?

Female: Break right ampoule, agi­tate one minute.

What is the next step?

Female: Break mid­dle ampoule, wait for color. Break left ampoule, let color trans­fer to lower layer.

Okay, so we’re agi­tat­ing it. The point of it is that this is, like I said, prob­a­bly the most pop­u­lar form of test­ing that is going out on the street when­ever you have a solid drug dose. There are ones for mar­i­juana. There are spe­cial­ized ones for dif­fer­ent things that peo­ple run into – heroin. That’s there. Now we’re going to hit that mid­dle one, okay. Wait for the color to develop, that’s what it says. And then the last one, it’s there. As you can see it is kind of orange thingy, and I’ll pass it around so that every­one can see it. This is a neg­a­tive. It is kind of a blondish type of color that’s there. You can see because they want to make it very easy for street cops to know — pur­ple means bad stuff, means mar­i­juana, means that you got it there. I am going to pass this around.

So this is how you would do it out on the street. I am going to give you each one of these. Okay, you are going to be my testers and we’re going to see whether or not you go to jail. Are you ready? What we’re going to do is take a lit­tle bit more. I want you to open up your pack­age there. We’re not going to jam it up with a whole bunch of stuff but we’re going to put some of it in there if you don’t mind. Just a lit­tle bit more. Then what you are going to do is shove it with the load­ing stick, the high-tech load­ing stick down to the bot­tom, please. Are you ready to go? That’s prob­a­bly good. Now, you do the high tech load­ing. Your fate is in your hands, my friend.

What we’re going to do is we’re going to seal up the top. Just push it all the way down to the bot­tom. Break that left most ampoule. Go ahead, break it. Crush it with your fin­gers. Agi­tate it like it says. You don’t want to get the chem­i­cals on you. Do the same thing. Okay. You’ve done it for a minute, now let’s go ahead and crack the mid­dle one. And then what we’re going to do next is see whether or not it turns pur­ple and you go to jail. So hit that last one. Hold your breath. Okay, I’m pass­ing around one that I did imme­di­ately before this because it’s going to take about 30 sec­onds for it to develop. Pur­ple at the bot­tom. What you have to do is you have to take a look at it. This is a false pos­i­tive on a screen­ing device because of cof­fee. Yeah, you are going to jail. Look at this. I mean she’s done. For­get about it. That’s about as pur­ple as that guy’s shirt over there. Let’s pass it around and take a look at. Pur­ple. He’s done too. Thank you to our vol­un­teers. Let’s give them a round of applause.

I will pass around the rest of these kits. I don’t want to bring them back with me to Har­ris­burg. I have a bunch of them. And the high tech load­ing devices, let’s get those going around, too. The bot­tom line is, it’s just like John was say­ing ear­lier, that you have peo­ple who are being arrested or put in jail for even longer peri­ods of time because we as a defense bar have refused or have been scared to learn the sci­ence of it all. We need to learn the sci­ence of it in order to be effec­tive for our clients. At least in my opin­ion it’s not shame on the traf­fic cop, he’s there to do his job. It’s shame on us for not learn­ing it.

We want to start talk­ing about objec­tive ver­sus sub­jec­tive. It’s pretty sim­ple. Every­one knows what objec­tive means. It’s empir­i­cal. It is what it is. Then you have sub­jec­tive, which is inter­preted by an indi­vid­ual, poten­tially based upon bias, con­fir­ma­tion bias, and is sub­ject to inter­pre­ta­tion. It’s some­thing that is fun­gi­ble. It is some­thing that is vari­able. One per­son takes a look at a cloud and says “That one looks like a bunny rab­bit.” Another per­son takes a look at the same cloud and says “That looks like a tur­tle.” The third one says “a rocket ship,” a fourth per­son says noth­ing at all.

That’s the dif­fer­ence that’s there. In sci­ence and what we need to demand in the court­room is to get away from this hocus pocus, this make believe, this sub­jec­tive sci­ence that is going on out there, and we need to move more towards the objec­tive part of it. That’s only going to come by us forc­ing it as a defense bar.

 

The above is Part Two from a lec­ture given by Attor­ney Justin J. McShane before the North Car­olina Advo­cates for Jus­tice “Advanced DWI Sem­i­nar”.  This sem­i­nar hap­pened on Feb­ru­ary 26, 2010.  It was orga­nized and hosted by John K. Fan­ney, Esquire of  Fan­ney & Jack­son, P.C. The fol­low­ing is a tran­script of this video:

I get to talk about drug cases and drugs, and stuff like that. I get to go across the entire United States and have a lot of fun doing it. This is going to be a fun sem­i­nar. I hope it is going to be inter­ac­tive when we can get in the mood — I get to talk about when peo­ple get high.

[Music — Afroman]

What we are really talk­ing about is ana­lyt­i­cal chem­istry; how they arrived at get­ting the magic num­ber. The cool kids are doing the ana­lyt­i­cal chem­istry. What I mean by that is if you under­stand even the basics of it, it’s going to absolutely fas­ci­nate you to such a degree that you are going to do noth­ing but read about it and just become cap­ti­vated by it. If you can learn how to chal­lenge that magic num­ber, as I am going to start to show you, you can take off from here. Once you know how to do it, there is no stop to it. You are going to become that weapon of mass acquittal.

What we are really talk­ing about in ana­lyt­i­cal chem­istry is what is called chro­matog­ra­phy. Chro­matog­ra­phy is sep­a­ra­tion sci­ence. It’s how you take some­thing that is com­plex and divide it into its inde­pen­dent parts. That’s chro­matog­ra­phy. It is an old sci­ence by SVELT. At the base, what you are doing is tak­ing com­pli­cated mix­tures, such as blood, which has a whole bunch of stuff in it, and you are look­ing to sep­a­rate it out into its  parts so you can fig­ure out how much ethanol is in it, or how much ben­zoli­do­cane is in it, or THC, Delta 9 THC. Chro­matog­ra­phy is sep­a­ra­tion sci­ence; it comes from the Greek words “chroma,” mean­ing color and “graphein,” which is to write. It is basi­cally lab­o­ra­tory science.

I am going to offer these to be the basic issues always ignored and things that we are going to talk about this morn­ing. The dif­fer­ence between a screen­ing and a con­fir­ma­tion test, foren­sic ver­sus non-forensic test­ing, and I mean that not from your state scientist’s point of view because they think every­thing is foren­sic because they are doing it. I am talk­ing about, in terms of the sci­en­tific com­mu­nity, the hard-core sci­en­tific com­mu­nity — there is a big dis­tinc­tion between those two. When you have a solid drug dose that often accom­pa­nies a DUID case, some­one gets pulled over dri­ving under the influ­ence of drugs and they find green leafy veg­eta­bles or white pow­der, that is, of course, we can’t ignore as prac­ti­tion­ers.  But one of the biggest ques­tions that is there is how on Earth did they actu­ally know that the white, off-white, chunky sub­stance is crack? That is a big question.

If you sit down and start to really think about it, as we are going to do with our time together, you are going to start to see some holes that are poten­tially there in the way they do their test­ing. Can they prove that the drug was actu­ally what it was or what they say it is in the solid dose form?  And of course Melendez-Diaz. Melendez-Diaz is, of course, the case from the United States Supreme Court, later there was Briscoe vs. Vir­ginia, which said the lab ana­lyst actu­ally has to come in and tes­tify. No longer can they do it by way of affi­davit and a piece of paper says you’re guilty.

What we want to do is take a look from the out­side in because we are out­siders. Has any­one here ever been to their state lab? Has any­one asked to go and inspect their state lab, to take a look at it? It is some­thing that maybe you folks should take a look at, because you would be amazed when you go in there and take a look at it.  First, it is great cross-examination ques­tion there where you can develop who they allow in the lab. You can ask them, “Can I come to your lab?” and they say, “No.” Then you find out that they let the Cub Scouts in and the Boy Scouts and any­one else but not defense attor­neys. There is poten­tial to show some bias that they are play­ing, not for the team of sci­ence, but rather for the team of con­vic­tion. That’s an impor­tant thing.

Lab­o­ra­tory analy­sis really breaks into not that many ele­gant things. Specif­i­cally what we are going to be talk­ing about here is the types of tests. There is screen­ing ver­sus con­fir­ma­tory. There is qual­i­ta­tive ver­sus quan­ti­ta­tive — quan­ti­ta­tive is how you arrive at that magic num­ber, the .162, qual­i­ta­tive is how you sep­a­rate out or can tell if it is cocaine ver­sus mar­i­juana ver­sus ETOH. That is called the qual­i­ta­tive mea­sure. Finally, there is objec­tive test­ing ver­sus sub­jec­tive testing.

The first thing I want to do is talk to you about col­ori­met­ric tests, or chem­i­cal color tests. Most vari­eties that are here, and they are truly screen­ing tests, are the Mar­quis Color, Cobalt thio­cyanate and Duquenois-Levine Test. Those are the three most preva­lent types of tests that are out there. What they are is very sim­ple. What it is, they take an unknown agent, what­ever it is, this green leafy veg­etable, they apply the agent and it changes color. That is all a col­ori­met­ric test is. It is a screen­ing test. What that means is that it has a high rate of false pos­i­tive, that means that is has the poten­tial of report­ing some­thing to be mar­i­juana that is not in fact mar­i­juana.  But it is designed, and it is sup­posed to have a low false neg­a­tive rate, which means that if it is not then it’s not. The bot­tom line is, even the best ones out there are not fool proof. It is a great illus­tra­tion of the dif­fer­ence between a screen­ing test and a con­fir­ma­tory test.

 

The above is Part One from a lec­ture given by Attor­ney Justin J. McShane before the North Car­olina Advo­cates for Jus­tice “Advanced DWI Sem­i­nar”.  This sem­i­nar hap­pened on Feb­ru­ary 26, 2010.  It was orga­nized and hosted by John K. Fan­ney, Esquire of  Fan­ney & Jack­son, P.C. The fol­low­ing is a tran­script of this video:

My name is Justin McShane. I am from Har­ris­burg, Penn­syl­va­nia. That’s our state cap­i­tal, not Philadel­phia or Pitts­burgh. It’s right in the mid­dle of the state. As John ref­er­enced, National Col­lege of DUI, I am a mem­ber of. If you have ques­tions at all about the blood test­ing related to cases, that’s what I spe­cial­ize in. That’s kind of what I am known for. Just shoot me an email and you can con­tact me through my twit face, you know, what­ever social media that’s out there, or through the web­site that is there.
The topic of this talk is “If You Want Blood You’ve Got It: Under­stand­ing, dis­cov­er­ing, pre­vent­ing errors in blood test­ing.” That is a nice title but the real title of my talk is going to be about how you need to start using experts and how an ana­lyt­i­cal chemist can be your best friend.

I would like to set the stage if we could just by very sim­ply lis­ten­ing to the Bare Naked Ladies.

[Music — The Big Bang The­ory Theme Song]

Bang! Okay, that’s what this sem­i­nar is going to do for you. We have such a star-struck, great lineup of speak­ers who are here through­out the day that you have heard about. This moment in time, hope­fully you will look back and say, “My good­ness, this was the big bang in my DWI career.” That’s what we hope to do.  And I am here to talk to you about ana­lyt­i­cal chem­istry and specif­i­cally about that magic num­ber that they pump out whether it is from a blood test, or if it comes from a breath test. What we are basi­cally going to do is take a look at blood test­ing in great detail.

Now, blood test­ing, I under­stand, is about 1% of your state cases, from talk­ing to John and a lot of other peo­ple. The rea­son you are you going to start see­ing a lot more blood cases today is num­ber one, seri­ous acci­dents; num­ber two, you guys are doing a great job chal­leng­ing breath test cases. They know, the eas­i­est thing in the world to do is scare you with words like “gas chro­matog­ra­phy” and stuff like that.

Is there any­one in this room who has an ana­lyt­i­cal chem­istry back­ground? See, this is amaz­ing. I go all across the United States and give this type of sem­i­nar — there is maybe one per­son who has ever raised their hand. Just to give you a background.

[inter­rup­tion – mur­mur about the peo­ple with ana­lyt­i­cal chem­istry background]

Two, great.

The whole point of it is that we, as lawyers, did every­thing we could to avoid sci­ence as much as pos­si­ble. But, if you under­stand sci­ence, sci­ence is great. The truth and the best way to win these cases is through sci­ence. The day and age of smoke and mir­rors is over and done with. The sci­ence is actu­ally on our side. One of the things you will note when you start to try to present more sci­ence in the court­room, in a legit­i­mate man­ner, the more they will resist your efforts to do so. They will try to exclude your experts, they will try to tell you that you don’t need dis­cov­ery, and that’s exactly, pretty much, what you are going to run into.  But what you have to do is remem­ber this quote from Robert Frost. I believe in this quote, it hangs in my office, that twelve or six mem­bers of the jury, do you have twelve or six? Twelve. They are actu­ally there to judge who has the bet­ter lawyer. That comes through sci­ence, and the hon­est pre­sen­ta­tion of sci­ence. Sci­ence is the truth, sci­ence is the defense. Does any­one ever watch the show The Big Bang The­ory at all? It’s a great show. They have a motto that says, “Smart is the new sexy.” Well, smart is the new not guilty in DUI defense. Play­ing hide the ball, smoke and mir­rors and only try­ing cases that are refusals or ones that are “Who’s the dri­ver?”, that only gets you so far.

I am going to show you in this pre­sen­ta­tion how you can chal­lenge the sci­ence that is being pre­sented, force it to be shown for what it is, both its lim­i­ta­tions and its good parts, and to start tak­ing this back and mak­ing it so it is a not guilty.

With the objec­tives that we have here and if you present it, and I do this all the time, I do it in dif­fer­ent states and have the plea­sure of going around the United States.  If you start to show a jury the sci­ence you can use that “CSI affect” that we all know about to your ben­e­fit, where at the end of the day, you present it to them in an hon­est way and you show the lim­i­ta­tions of the test­ing — juries get that. You’re going to empower them not to ignore things, which are our tra­di­tional method, but to vote sci­ence at the end of the day. It is very impor­tant to take a look at that.

My objec­tives today…and just so you know, there are hand-outs that I think every­one has one here. There are only a cou­ple of new slides that I have added since I was out in Seat­tle. Basi­cally, this is being taped by both you good folks and I am also tap­ing it. It will be on YouTube at some point in time along with the Pow­er­Point slides being inte­grated. The rea­son I tell you that is because I want you folks to be exposed to this. I want you to sit back and lis­ten. Don’t worry about tak­ing down notes, okay?  Every­thing is in there. If you have ques­tions, I am happy to answer it all. It’s going to be like a for­eign lan­guage to us because we are all lib­eral arts majors. That’s what I was too, a lib­eral arts major. The whole point of it is not to become a mas­ter or an expert, in and of your­self, but to know what to look for so you can call up the expert or you can ask the ques­tion of John and some other folks that you have in this great state here, as far as what to do.

Our objec­tives here are to help you iden­tify cur­rent issues in defend­ing the cit­i­zen among us accused of a DUI offense; to intro­duce you to the sci­ence of ana­lyt­i­cal chem­istry; expose you to an idea of how to totally frus­trate a DA because you have learned the sci­ence and he has absolutely no idea about the sci­ence; to learn how to force bet­ter deals because what you are look­ing to do is cre­ate that knowl­edge gap. A DA is not sup­posed to lose a DUI case. How many peo­ple used to work in a DA’s office? If you lost a DUI case, didn’t you get made fun of? You aren’t sup­posed to lose those cases. It’s like los­ing a hand-to-hand deliv­ery case. It just doesn’t hap­pen. What you do is get them embar­rassed of the fact that they don’t know what you know and what you have been exposed to, and it is going to force a deal at the end of the day.  It will teach you how to bet­ter cross-examine experts so you know exactly what you are talk­ing about.  And then start using expert witnesses.

By a show of hands, how many peo­ple have ever used an ana­lyt­i­cal chemist or a phar­ma­col­o­gist in their DWI tri­als? We have 4 out of 98.  If you have an ana­lyt­i­cal chemist and a phar­ma­col­o­gist and some­one who is well-versed in the SFSTs, you are going to be an absolutely deadly per­son. Basi­cally, what we are going to be doing here together is learn­ing how to become that most awe­some weapon of mass acquit­tal. So become that weapon of mass acquit­tal. Let this be the spark of where you want to go with your career because not guilty’s is what we are sup­posed to do, and I am going to show you how we can do it.
