Judge In Tucson DUI Cases Orders Prosecutors To Get Intoxilyzer Source Code

Tuesday, October 28th, 2008

A Judge in Tucson, Arizona has ordered the prosecution to get the Intoxilyzer source code from CMI, and produce it in electronic form so that it may be tested. The Tucson Citizen reported as follows:

“Every lawyer in this room should be concerned about CMI’s unwillingness to follow the court’s order,” Bernini said.
Bernini said CMI must hand over its source code in electronic form by Nov. 10.
CMI has a policy of releasing the source code in a printout if the recipient agrees not to release it to anyone else.
Defense attorneys asked for – and Bernini ordered – the source code in electronic form so they can test its veracity.
“This information would be available with ease in an email,” Bernini said Monday.
From all appearances, it seems that the attorneys involved in this case handled it expertly. This case may be on its way to setting a national benchmark.
My prediction is that the ruling holds up, CMI refuses to turn over the source code and Arizona ceases use of the Intoxilyzer all together within 2-3 years. CMI has dug itself a huge hold, and their only alternative may be to fold and reemerge under another corporate entity or structure.
If, as the lead attorney in the case speculates in the article, CMI knows that it is hiding something in the source code, then they would be wise not to divulge it and fold instead.

Why Intoxilyzer Source Code Matters In DUI Cases

Saturday, October 11th, 2008

In DUI cases the state wants everybody to believe that the Intoxilyzer machine has been tested. Because it has been tested with known standards of alcohol, they want us to assume that it can also analyze an unknown. They also want us to assume that the software has no flaws or bugs that could render a false high under various conditions.

The source code of the Intoxilyzer matters because we need transparancy in the justice system. In Arizona, a first time extreme DUI (read as about average DUI of .150) requires 30 consecutive days in jail. This is serious. It also creates a permanent record. Very serious.

I believe that the constitutional rights of people accused of drunk driving are more important than a corporation’s “interest” in the work product of their software.

If CMI continues to refuse to divulge the source code without conditions or exceptions, then law enforcement agencies and prosecutors should do the right thing and stop using them. Our government wastes a vast amount of taxpayer money. If we took all the Intoxilyzers in Arizona and threw them out (or recycled them), the amount of money lost on those machines would probably be less than the cost of convicting innocent people (they lose their jobs, stop paying taxes, etc), and the cost of litigating the cases combined.

If they don’t let it out, then we should throw it out.

DUI Breath Tests Not Accurate

Sunday, October 5th, 2008

What most prosecutors don’t seem to understand or want to acknowledge is that breath testing in DUI cases can be extremely inaccurate. It has been scientifically proven that the Intoxilyzer machine has the following accuracy rates when it comes to reporting an alcohol content that corresponds(in approximates) to the actual concentration in a person’s blood:

  • 11-percent of the time the machine is accurate
  • 44-percent of the time the machine underestimates the person’s blood alcohol content
  • 44-percent of the time the machine overestimates the person’s blood alcohol content

How is it that a machine that is that prone to getting it wrong is used in the justice system in DUI cases? That is an excellent question and one that many jurisdictions are now seeking to remedy by providing blood tests instead of breath tests.

There is no good breath test machine. Breath testing for alcohol is a crude enterprise hardly worthy of the label “science.” Until breath testing is eliminated or improved from its current state, there will be people wrongly accused and convicted of DUI, and there will be people wrongly exonerated of DUI.

Until organizations such as MADD and prosecutors offices open their eyes and demand a stop to this injustice, innocent people will face the ordeal of a DUI trial in courtrooms across the country daily.
