I imagine that the relatives of the thousands of people killed each year by drunk drivers would disagree with you on police spending more time preventing "violent crime". If you had to go to the morgue to identify the mangled bodies of loved ones killed by a drunk driver, you might decide that this IS A VIOLENT CRIME!
B M, please don't hide behind the old arguement of a couple of beers with dinner. According to the website below, 2 beers over an hours dinner for someone weighting 180 lbs results in a blood alcohol of .02% (well below the legal limit of .08). Try 5 beers in an hour or 4-5 glasses of wine in an hour. That will break the magic .08 barrier and is well above the casual drinking you mentioned.
Not only do these stops catch the DWI's, but looked at the ones with no license, no insurance, under revocation, open warrants, etc. I hope the police keep it up and make these stops more often.
