DUI Defendant Wins Source Code to Breathalyzer

MyrddinBach writes "CNet's Police Blotter column looks into a Minnesota drunk driving defendant case with a twist. The defendant says he needs the source code to the Intoxilyzer 5000EN to fight the charges in court. Apparently the company has agreed to turn over the code to the defense. 'A judge granted the defendant's request, but Michael Campion, Minnesota's commissioner in charge of public safety, opposed it. Minnesota quickly asked an appeals court to intervene, which it declined to do. Then the state appealed a second time. What became central to the dispute was whether the source code was owned by the state or CMI, the maker of the Intoxilyzer.'"

      no, not at all. as a matter of fact, quite the opposite. in most states you will never be informed that you can in fact have a blood sample taken. you will blow on a machine like this and that will be all she wrote for you. had i know this, i would have asked for the blood test. there are many reasons why. first off, when you ask for a blood test (you usually have to provide (call) the doctor to take the blood sample, yourself, and pay for the doctor) you have about an hour, give or take, before the doctor gets there. this little bit of time might mean the difference between passing and failing. second, if you take the blood test, there is evidence that you can use in court in your defense -- whereas, if you only do a breath test, the only evidence that exists if it goes to court is a print out that the police have with a number on it.
       
      i blew on a draeger alcotest 7110 mkiii, and let me tell you, i got totally pwned. the guy that blew in front of me was way way over the limit and smelt of pure scotch. sure, they swapped the mouthpiece before i blew, but not the tube itself. well, this unit, inbetween tests, will draw air through the top of the machine to clear out the chambers for the next test. so, basically, when i blew right after him, i am convinced that there was still residual alcohol inside of the tube which in turn got me arrested and a dui on my record.
       
        whats funny is, at the time, the draeger alcotest 7110 mkiii was being contested in 4 states. i was going to fight it, based on those grounds, until i saw a case from a county in my same state. this guy blew the legal limit, and went to court to challenge the results. you see, with most breathalyzers the state /has/ to calibrate them every so often, and, if they cannot produce the documents proving the last time it was calibrated, you walk. that guy tried to get by on that paired with the residual alcohol stance. see, the draeger is actually quite advanced, it does the two most popular tests. infrared spectroscopy and electro chemical cell. but, inbetween tests, the machine does a self diagnostic. well, in this poor guys case, the state couldn't produce the documents showing the last time it was calibrated, but, the judge said, since the unit preforms a self test every time, that was good enough. sent him to jail for 4 years, first offense, driving at exactly the legal limit.

      Actually, it's more complicated than that. Most of the breathalyzer machines actually measure the absorption of light sent through a chemical that changes color when oxidized by alcohol. From that absorption number they are able to estimate the the concentration of alcohol in the sample in the machine and, from that, the concentration in your breath. The concentration of alcohol in your breath correlates with the concentration of alcohol in your blood because the alveolar membrane in your lungs is extremely thin and highly vascularized (it must be this way to permit gas exchange for respiration). The alveolar membrane is of a similar thickness in people of all body types and would probably not be a source of error. The only possible exception to this might be someone affected with fibrosis, which would actually lower the measured amount.

      That being said, this process that the breathalyzers go through requires a lot of assumptions which often are not true in all cases. In fact, I've heard of Chemistry/Biology grad students making quite a bit of money by offering their expertise to challenge (often successfully) these assumptions in court.

    Never wrong? BAC and the breathelizer estimate aren't the same thing.

    They have on average a 20% margin of error (a .8 result could actually be a .65 or .96), and make a number of assumptions which may or may not be true:

    lung capacity

    got diabetes, you are far more likely to create acetone which breathilzers may read as alcohol. Further a low blood sugar reaction may produce impairment results outwardly similar to driving drunk.

    physical activty. get the blood pumping right before the test and the levels drop.

    Many breathalyzers assume that the tested individual is an average person and do not take into account sex, height, weight, metabolism and whether that person has just eaten. Furthermore, many breathalyzer tests assume a specific ratio (2100:1) between BAC and breath alcohol content in order to make its conversions. As this actual ratio for a particular individual may vary between 1700:1 and 2400:1, a reading of 0.08 could actually mean a blood alcohol content of between 0.65 and .09. This significant gap could be all the difference in a DUI case since a reading of 0.65 would also require evidence of impairment, often in the form of field sobriety tests.

    Submit evidence that you don't fit to those norms and you may get off. Anyways defendants in drunk driving cases are charged with two offenses: (1) driving under the influence of alcohol and (2) driving with a blood-alcohol level in excess of a given level. They aren't actually charged with poor driving, though it may be a symptom of the impairment. Per http://www.california-drunkdriving.org/alcohol_tol erance.html there have been studies showning that alcoholic with BAC levels in the leathal range not showing any signs of impairment. So anyone charged with driving in excess of a level doesn't mean that they are actually impaired.

    Law enforcement tends to charge people with easy crimes, such as speeding or having a high BAC, while ignoring people with truley reckless behaviour: large differentals in speed, failure to signal, aggressive lane changes, and following too closely. I'm not defending those who drive after drinking, but feel it is important to note that the typical way that evidence is collected is flawed.

  46. components of products in question by belunar · · Score: 4, Interesting

    When I say this, I know Im not a lawyer. I dont know how accurate my point of view is, this is just my interpretation of what Im seeing of this case.

    Ignoring the reason for the case, drunk driving, Im looking at what they wish to use as evidence. In this case the testing equipment used, IE the breath tester. If a test, breath test, blood test, etc, is to be used in a court case, the equipment used for said teast could also be called into question and itself be on trial. How the equipment is handled or mishandled, manufactured, operates, used, etc, can all be called into question, in whole or part.

    What if this turned out to be a physical component that was in question? Would the state have the same objections to the defence wanting to review the product in question?

    For an example, say this was a car, not a breath tester, that was in question, and this car was known to have a faulty gas tank. Would the state say "No you can not get this information from the manufacturer, becase the state owns that car and it is all ours now." or would they let it through?

    The way I see it, the software a device runs on is just as much a part of said device as a bolt or a battery. If they can give legal reasons for questioning a screw that holds something together, or a gear that turns a part, then they can question the software that runs it also. Copyright does not factor into this at all, which is what the state is trying to say.

    This is not being done to illegaly reproduce the code, this is not being done to copy the work done into another product, this is being done to anaylise its effectiveness, see where bugs are, etc, for a case already in a court of law. If they were trying to copy the code, resell it illegaly, or use it as part of another product, I could see copyright applying. Not in this case.

    Just my point of view in this case.

Maybe the people that are extremely drunk are doing it a higher rate than those who've "only had a couple beers" but the people who've "only had a couple" are killing people at a significantly higher rate than people who haven't had anything to drink. This mindset that if you're not stumbling drunk then you're fine to drive kills so many people.

      According to your chart there is no percentage of alcohol, no matter how small, that does not impair. It has warnings about .01%. Some people can get that from mouthwash.

      The other thing about these charts is that your body is disposing of the alcohol at (give or take) the rate of about 1 drink per hour. So if he's a large man like me (275 lbs) and had those drinks over the course of 3+ hours at a bar shooting pool, he's probably just over the .08 limit.

      Realistically, "Impairment" is a difficult thing to measure. But I find it hard to believe most of what I've read in the last 15 years since "Drunk Driving" became a political crusade. As with anything else, once that happens it's hard to find any hard data or untainted statistics on the subject.

      When I was a kid in high school, the material we had dealing with alcohol and tobacco seemed more realistic. For example, we were told that the average person's body could dispose of the tar from 3 cigarettes a day. **We were also told that it was unhealthy, and that you would almost certainly become addicted and smoke more than that.** But that seemed logical given that people don't worry about the ill effects of sitting around a campfire. But now we are told that even minimal exposure to someone else's smoke will do irreparable harm, cause cancer, etc. That doesn't seem likely for someone still healthy enough to sit around the campfire.

      Alcohol statistics are getting there too. A buddy of mine was T-boned by a driver who ran a stop sign. The driver got off lucky, because my buddy was just on the minimum limit, and was faulted for the accident for being intoxicated. No need to look at the scene - he's been drinking so he's automatically guilty. Another banner case of alcohol abuse for the statistics.

      It's not relevant, but I'll throw it in for the tear-jerker crowd. I have a sister-in-law who is missing a leg from a drunk driver. I have a friend who has major spinal injuries from a drunk driver. Yes those are tragedies, and I would show no mercy on a .22 driver flying around town out of control. But these people weren't injured by a .08 driving 2 miles home doing the speed limit. And no amount of hysteria, falsified studies, road blocks, check points, random searches, and nit-picking people over 1 or 2 drinks are going to prevent this sort of thing.

      Another disclaimer - I've never had a DUI myself, and I don't drink anymore (I'm a sobered up alcoholic). I just believe in approaching problems rationally and realistically instead of hysterically.

We're prepared to throw away trillions in certain areas for little to no benefit while adamantly refusing to spend enough on the huge bang-for-your-buck things.

    That 16k/year statistic is bogus. Most of those accidents would have happened anyway. Obviously alcohol is not necessary for an accident, and nobody has proved that further lowering the BAC saves lives. Besides, most of the drunk driver related deaths were already against the law. Lowering the BAC further won't stop any of those deaths. Those drivers were already willing to break the law. Tweaking the law won't make them more responsible.

    I really don't get your attitude. You act as if it is wrong to place a dollar amount on human life. Well it is done all the time. The dollar amount is quite low, too. When designing roads, cars, traffic rules, etc. a tradeoff must be made.

Society has decided that that much lost time isn't worth a human life. We could give everyone a free safety upgrade to their car complete with 5-point restraint, interior crash protection cage, and so forth and probably save 30k lives/year but it just isn't worth it.
