and most don't kill anyone.

legalizing drinking for kids aged 18 to 20 will just reduce the # of them who get arrested.

the major problem w/the high drinking age (as you know) is it forces these kids to drink in situations where their consumption isn't monitored or regulated. if they drink in public places like bars and restaurants they can be cut off from service by tenders in licensed facilities (who have a duty to cut them off when overserved). as of now these kids are drinking at private parties and other informal gatherings where no one monitors them.

the kids would still have their house parties even if they could go out to bars but there'd be less of that. and more of them drinking where they can be monitored and controlled.
