Arizona has seen the replacement of most of its Intoxilyzer
5000 alcohol breath testing machines with a newer model
from CMI, the Intox 8000. CMI, according to prosceutors,
refuses to release the source code used to program these
machines. So far, the machines are being used in DUI trials
in Arizona, and people are being convicted based on the
reading from these machines. There looks to be brewing a
battle over whether the defense is entitled to actually
confront the witness against them (in this case the
machine), or whether the Arizona courts will allow the
admission of the results without a meaninful opportunity by
the defense to explore how the machine arrived at the
results. Some Arizona jurisdictions routinely use blood
tests instead of relying on breath testing machines at all.
These include DUI arrests made in Scottsdale, Chandler,
Gilbert and Mesa.
