Exactly! Prohibition works really well.

Now if only we could figure out what state that coke, heroin and meth are still legal in!!

I stated that I wouldn't advocate for a national prohibition on guns mostly because I think it wouldn't work and I support gun rights. But if you were to try banning guns, it'd have to be a huge national effort and not just a few states.
