Lots of cops are just jerks. I don’t particularly like cops, for a variety of reasons. And I work for lawyers who represent lots of DWI clients so actually DWIs are good for our business. However, I know how much they cost people - fines, court costs, assessments and treatment, lawyers’ fees, insurance, sometimes lost jobs. And it brings in a lot of money for governments. Just way easier to not take the chance of even having one drink and driving. As for registration violations and stupid crap, usually the DA will end up dropping them but you still have the aggravation of going to court, missing work, etc. It would help if we had more cops with common sense.
I know it’s all about the revenue generation. It’s certainly not to reduce fatalities. I mean, if most drunk drivers which cause fatalities have a BAC of >.16, then how does constantly lowering the permissible BAC help?
Then again, I’ve seen the logic of people in charge creating a solution before. In the navy, we had to wear hard hats during certain operations because someone chipped their tooth. Where I work now, management decided to change the locks after a contractor got into a room we left unlocked. Maybe those are the type of people we let write our laws.
