I got caught up in a roadblock a few years ago in South Boston. I had had a couple of beers at a restaurant but was absolutely not under the influence. Nevertheless, when the cop shined the flashlight in my face and asked me if I had had anything to drink, I lied to him and said that I had had nothing to drink. He then thanked me in waved me through.
My cop friend told me that if I had told him I had a couple of beers, there would have been a 100% chance of him pulling me out of my car (in front of my wife) and placing me under arrest for DUI.
To this day, I still feel crappy about lying to the police but I know the alternative would have been a night in jail and quite possibly a criminal record that would have precluded me from holding the job I have currently.
With respect to DUI's, this country really is a lot like Nazi Germany. Of course, all these roadblocks and sham DUI arrests of decent people who had the misfortune to have a glass of wine on the wrong night, do absolutely nothing to stem the true problem of drunken driving. People with an alcohol problem will continue to drink and drive regardless of the consequences. We hear all the time of people with multiple drunk driving arrests who go right back to it as soon as they are let out of jail. Even taking their license away doesn't stop them. Serial drunk drivers almost invariably also get charged for driving without a license!
If you really want to put a stop to drunk driving, do away with the roadblocks and the persecution of decent people and just put unmarked cruisers out on the highways or park them at bars and taverns. You will very quickly be able to identify the drunk drivers as those will be the ones swerving all over the place and being a menace to other drivers.
As the rest of traffic enforcement, the point isn't to catch the most dangerous offenders. It's to catch the most offenders.
To figure out why, just follow the money.
If you weren’t under the influence, then you shouldn’t have had an issue with the tests. You could have walked the line and passed the Breathalyzer.
I’m sure they will come up with a DUI exception to the entrapment defense as soon as it gets to the Supreme Court.
