I just had an opportunity to visit on the phone with one of the prosecuting attorneys for the City of Minnetonka. Somewhat to my surprise this person made a remark to the effect that over the past few weeks the number of DWI arrests is down. There was some speculation about what the reason might be, but the real answer is that nobody really knows why.
I can guess that the economy might have something to do with it. Even if people might be still drinking, doing it at home is certainly cheaper. Another issue of course is that DWI arrests have become more difficult from the point of view of the police officers, since there has been a great deal of concern lately about the accuracy of the breath test. If the officer wants a blood test, a trip to a hospital might be required. That takes a lot of extra time.
