Breathalyzer Source Code

I've heard about this trick where folks who get nabbed on DUIs and DWIs get the case thrown out by demanding to see the source code that the breathalyzer runs to measure the alcohol level. Companies usually refuse this request because source code is almost always a tightly held trade secret for proprietary applications. (As opposed to open source applications where the code is available so others can make adaptations and review the functionality.)

The code for the "DRAEGER ALCOTEST 7110 MKIII-C" device was submitted for analysis and the summary paragraph of the report says, "There is no doubt that the Supreme Court should declare this machine to be unreliable. If this happens, based on an agreement entered into over 4 years ago between the State and Draeger, the taxpayers of New Jersey can recover the almost $7 million spent on these machines."
