I've represented hundreds of DUI clients. none of them have been violent or hurt anyone. i am familiar with cases my colleagues have had as well. There are maybe one or two of the hundreds of cases that actually involved others being hurt. Clearly, thats one or two too many, but it doesnt change the fact that percentage wise, most DUIs dont result in injury.
Truth is most people get DUI's not because they're driving erratically, but because they smell like they've been drinking after some faux stop...
I got pulled over about two months ago on my way home from work at 2am and the first thing out of the cops mouth were "how much have you had to drink tonight" I told him nothing, he called bullshit and said "I'm going to ask you again" and I told him nothing. Then I asked him why I was being pulled and he told me "oh your license plate light is out." So it is quite obvious he pulled me because it was 2am and he was just "fishing" for anyone to arrest.....
I suppose my point is the majority of those who get DUI's don't get them because they're a danger to anyone or anything - they get them because cops like to "fish" and when people smell like beer they're screwed.
That's why after I've had a couple/few I always make sure to wash up and brush my teeth.
