That's fair enough.
Of course, one of the most effective ways of testing this is the breath test itself, using the equipment that is in place right now. With the addition of this device, would a negative test on that stop the police officer from having the ability to take a regular breath test?
Is it necessary for the officer to have a positive test on the passive device before he can go into the next one? Don't you think that might be a challenge if the passive detection device did not pick up the alcohol, and then the police officer tried to go to the next step? That might be something that I would guess would be argued in court at some point. What do you think?
