If that is the leftist logic, then let us go one step further, enact an Islamic theocracy like Saudi Arabia. They have very low crime and even lower HIV rate. Harmful cigarettes and alcohol is banned. Healthy, very little crime and very orderly society compared to the wild west free Americans./sarcasm
The only difference is they get kinda' close and you'll not be finding any RPG armed young buck Yemenies doing something stupid like that!
