Zero tolerance? That's great..... if the person is actually drunk. I have a friend that blew a .005, but was arrested, charged, and convicted. It was psychotic, we hadn't even made it to the bar yet. The cop decided that he failed the sobriety "tests" and locked him up. Then he asked me if I was sober enough to drive his car. I told him that the way they handled things in this hick town, I'll never drive a car here. That cop left me standing on the side of the highway. THAT is the REAL problem with intoxication laws. If a cop wants to be an ass, he can and will. It's like the day I got a ticket for speeding in a school zone.... But I got it in the mail???? Before that I had no clue that a school bus driver can report you resulting in a ticket. Thing is, I'd never been within 20 miles of the school. It took a couple weeks, but the ticket was dropped by the officer that wrote it, only after he got a vehicle description that didn't match my car.
It's very PC to say that we need to crack down on drunk drivers, but the reality is that those who want to drive, WILL!! whether they have a license or not! The punishment around here is usually a couple days in jail, a couple THOUSAND dollars, high risk insurance rates, difficulty getting jobs, etc, etc, etc. The last thing we need is to let that get any more out of whack. It's cheaper to be convicted of cocaine possession! If you are a small town that doesn't want any "drunk" driving, OUTLAW ALCOHOL AND SHUT DOWN ALL BARS..... Oh, that would reduce your town's municipal income by 80% and half your citizens would move away? Too bad! Have the cake or eat it.
