that's fine, but we still must balance a. the human costs of criminalization with the perceived human benefits and b. further assess causality: the harsher penalities may not be driving down the rate and recidivism, it could be the public health campaign, something else, etc.
It is unquestionably both public education combined with deterring penalties that have driven the number of drunk driving deaths and maimings down in recent years--DRAMATICALLY. It would seem by any reasonable measure that the criminalization of grossly irresponsible behavior of getting behind the wheel of a multi-ton vehicle moving dozens of miles an hour while under the influence, measured against the lives and limbs saved SHOULD be a no brainer.
In my .11 DUI episode (plea bargained down after 18 months to a wet reckless, because I insisted that there was a possible lack of probable cause to stop me in the first instance defense), for a first time offense, I got 14 hours in jail, could not drive for a month, then six months of only to work and back and to DUI classes, 10 Saturdays at DUI classes plus a MADD session, can't drive with any alcohol in me for 3 years, and have about $15,000 over time in higher insurance premiums. Is that penalty harsh enough in your opinion Badger?
