A Minnesota man accused of drunk driving has sued to see the source code of the Intoxilyzer 5000EN machine that busted him, and the state Supreme Court is allowing the request to go forward.

His attorney told the paper, "The problem is, the manufacturer of the thing thinks they can hold it back and not tell anybody how it works. For all we know, it's a random number generator."

If they’re going to be accused based on what some machine says, then they ought to be allowed to challenge the accuracy of the machine. And they can't do that unless they’re allowed to know how the machine works.

Who is doing the QA work for these state certification programs?

What if the machine was off by a 100th of a BAC measurement? I applaud this effort, even if it is just a slick way to get out of a DUI.
