>Nobody wants to talk about the (in)accuracy of breathalyzers. That's because like every other bit of tech used to convict people it's designed to err on the side of convicting people not being accurate. If you want a laugh look up the sensors they use in the alcohol ankle bracelets. Then look up the OEM specs, calibration requirements, usage environment requirements and accuracy claims by the vendors and try and reconcile the two (several research papers have been written about this). The whole industry is lousy.
