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.'"

News: Breathalyzer Source Code Revealed 501 comments
Nonillion writes "New Jersey attorney Evan M. Levow was finally able to get an order from the Supreme Court of New Jersey forcing the manufacturer of the popular Draeger AlcoTest 7110 to reveal the source code. Levow turned the code over to experts, Base One Technologies, to analyze. Initially, Base One found that, contrary to Draeger's protestations that the code was proprietary, the code consisted mostly of general algorithms: 'That is, the code is not really unique or proprietary.' In other words, the 'trade secrets' claim which manufacturers were hiding behind was completely without merit." Following up an earlier discussion here, the state of Minnesota has (without explanation) missed a deadline to turn over the code for a different breathalyzer.

News: Judge Rules Defense Can Get DUI Machine Source Code 270 comments
pfleming alerts us to developments in Arizona on a subject we have frequently discussed (e.g. FL, MN, NJ): efforts in DUI cases to obtain source code to devices that analyze blood alcohol levels. On Friday a Pima County Superior Court judge ruled that the software that powers the Intoxilyzer 8000 must be revealed to defense lawyers. "Defense attorneys representing more than 20 people arrested on felony DUI charges agreed to consolidate their cases into one and to argue it before [Judge] Bernini ... The source codes are crucial because the Intoxilyzer 8000 sometimes gives 'weird' or inexplicable results ... Six other states have been battling CMI [maker of the Intoxilyzer] over the source code — Minnesota, Florida, Louisiana, Massachusetts, Tennessee and New Jersey... CMI has currently racked up over $1.2 million in fines in a civil contempt order for not disclosing the source code in Florida."

MN Supreme Court Backs Reasoned Requests For Breathalyzer Source Code 199 comments
viralMeme writes with news that the Minnesota Supreme Court has upheld the right of drunk-driving defendants to request the source code for the breathalyzer machines used as evidence against them, but only when the defendant provides sufficient arguments to suggest that a review of the code may have an impact on the case. In short: no fishing expeditions. The ruling involves two such requests (PDF), one of which we've been covering for some time. In that case, the defendant, Dale Underdahl simply argued that to challenge the validity of the charges, he had to "go after the testing method itself." The Supreme Court says this was not sufficient. Meanwhile, the other defendant, Timothy Brunner, "submitted a memorandum and nine exhibits to support his request for the source code," which included testimony from a computer science professor about the usefulness of source code in finding voting machine defects, and a report about a similar case in New Jersey where defects were found in the breathalyzer's source code. This was enough for the Supreme Court to acknowledge that an examination of the code could "relate to Brunner's guilt or innocence."

Yes, that is close to the reality.
In the case of drunk driving, most states have adopted the law that if you are driving a vehicle, you have then given consent to submit to the approved test to find out if you're driving under the influence of alcohol. When you are stopped and you're not sure of what your alcohol level is, you cannot refuse to take a breathalyzer test. As soon as you got your drivers license, you gave consent in advance to do this. If you refuse, you will find yourself in bigger trouble than you would have by submitting to the test. This implied consent is automatic in the case of anyone who drives a vehicle.

If you refuse the test you are denying them evidence to use against you in a criminal proceeding. You will have to deal with the civil punishment from DMV (typically a suspended license for a period of time and some civil $$$ penalties) but you are denying the state evidence to use against you at a criminal proceeding.
In most states they can't force you to submit to a chemical test of any kind (breath, urine, blood) except for a few limited sets of circumstances (accident involving injury or death, you previously agreed to the breath test and now they want blood, etc, etc). Yes, you will lose your license for awhile, but they probably won't have enough evidence to convict you of drunk driving. Whereas if you had submitted to the test you will probably be convicted (criminal record) and lose your license anyway.
Refuse the test unless you are 100% proof-positive that you aren't intoxicated. This doesn't even mean 0.08. In many states they can hit you with lesser charges at 0.05.

From your college chemistry course acetone has a C=O bond, while alcohol is a C-OH bond.
Cheap breathalyzers will use a chemical reaction to detect the alcohol in your breath -- often potassium dichromate (these are the ones that go from red to green with alcohol).
More advanced models (such as the ones the police would use, would use essentially spectroscopy to try to measure the resonant absorbance of the C-OH bond. This would not be fooled by acetone, which has a much different absorbance of the C=O (approximately 1700 cm-1 IIRC). There are also variants of this method.
If you are ever innocent and accused, get a blood test, which really is a quantitative direct measurement and can be confirmed, with very little chance of being fooled.
If you are not innocent, **IN THEORY** the easiest way to lower your reading is to silently hyperventilate prior to blowing. This would prevent equilibration of the alcohol in your bloodstream with the air in your lungs that you just breathed in and out. It is far from perfect, and I would strongly advise to never drive drunk, nor rely on this method.

I don't want my government spending my tax money and wasting time in court, to get convictions based on evidence from mysterious unaudited machines. Why? Because sooner or later, some defendant is going to want the mystery peeled back. Some defendant is eventually going to want a fair trial. Might as well give that fair trial to the first one, so that a bunch of expensive shit doesn't have to get re-done (or so that a bunch of guilty people don't end up walking free, simply because the cops used a defective machine that ended up collecting untrustworthy "evidence").
Keep mysteries out of court, from the start. Don't let a big list of convictions that depend on them, build up. The chances of the device being defective are probably pretty low, but you know there's gotta be some prosecutors with pits in their stomachs.

If this gun reading is the states main piece of leverage it's because this device conforms to some strict requirements defined by the state. So maybe looking at the code will show that it doesn't and that the machine is in fact illegal.
Lastly, if you ever get pulled over for something like this, don't talk. That is when they ask if you've been drinking, always say no. What does "drinking" mean? Well, it's not up to you to define this at that time. Let your lawyer handle it. Never tell a cop you might be breaking the law. Because once you've admitted that you have been drinking, they can ask you a whole bunch of other questions that can only hurt you. How much? For how long? Where at? Where are you going? With who?
Here's a sample:
Officer: Have you been drinking?
You: No.
Officer: I smell alcohol.
You: I haven't been drinking, officer.

As I've explained to my judge: essentially, states needs to learn that it is a very bad idea to sign contracts to acquire closed source devices to which they will have no access or ability to test. The same goes for voting machines.
Personally, I'm VERY conservative when it comes to DUI cases, and I very, very rarely side with the driver. But in this case, I've decided it's worth it to throw out a few of them if it means fixing "the system", not just for the intoxilyzer code, but for more important things like the voting machines.
On another note, I'll be writing a more thorough order requiring the use of the source code, and as one of the few law clerks around that has a CS degree, it'll get used by plenty of other judges. So if anyone has any suggestions on good, succinct public-policy based rationale, I would certainly like to read them.
Why it might actually matter (Score:4, Interesting)
I haven't seen anyone point this out yet, but there is a very interesting piece of information that matters here that he can get from the code. That is the assumptions about the blood-gas partition constant in use. What the machine is measuring is alcohol content in his breath (actually, content of a number of organics, but alcohol is usually the only relevant one). What it is reporting is the alcohol content of his blood. To get from one to the other requires a number of assumptions, most importantly about a number called the blood-gas partition coefficient -- which relates to how much of the alcohol evaporates out of blood in the lungs. The problem is that this number varies significantly from person to person, and even in one person over time. It is entirely possible he has a reasonable argument to make that the machine's assumptions about his partition constant are not correct. IIRC, the constant can ary over a factor of 2, occasionally more. So the question is, how conservative are the assumptions? How well do they match him?
It's a question of measurement accuracy, not just software bugs, and the software can inform greatly about how the measurement is taken.

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.
