A little off topic, but I'll lend some personal experience here. Aged 24, at a DUI checkpoint, I blew UNDER the legal limit, was very polite and showed no inability to drive safely. I was thrown in cuffs, notified I'm under arrest for driving while intoxicated, taken to a hospital, video taped, took my blood. Meanwhile I was sitting near people noticably intoxicated or apprehended for doing far more nefarious acts than I. Still in cuffs, the cop wouldn't let me fish my phone out of my pocket to wake my girlfriend up at 2AM to come pick me up at the hospital--so he made the call and of course scared the shit out of her. I was notified that if I was over the limit I could be charged for up to a year. I wasn't charged, nor had I done anything illegal.....however I was so petrified of my name being in the paper or otherwise defamed, along with losing my rights for a night. To this day I've never even gotten a speeding ticket, getting thrown in the back of a cop car was not something I enjoyed.
