Eubilides makes good points. I don't condone drunk driving. But let''s just say you have two beers after a long day of hard work. You drive home and get stopped because one of your tail lights is broken. The cop smells alcohol or thinks he does. You pass the field sobriety test. Meanwhile, another cop shows up, member of the local force's SEAT team. This cop demanda breathalyzer test. The machine, however, is defective, a not uncommon thing. You test a bit over the minimum allowed by law. you are going to have to spend thousands of dollars to fight this charge.
