slips, trips and falls are accidents. drinking and driving is a choice that puts others at risk.
if you make choices that put me and mine in danger, then I'm happy to see your ass get fined heavily. And if you do it again, I'm happy to see your ass lose its license to drive. And if you keep doing it, I'm quite happy to see your ass in jail for a good long while and I'll feel safer because of if.
Oh, and will you feel safer when guns are congregated in the hands of costumed super heroes? So it follows. I may have driven drunk, and if so I did not kill anyone. The abitrary designation of .08 or whatever the fuck is the issue.
