the problem in America is we don't control our borders worth shit.
smugglers routinely bring in drugs, guns, even PEOPLE!
This means that the black market is alive and well, so there's no reason for criminals to buy guns legally, they could be traced.
I think if we banned guns in the US, only criminals would have them.

plus we're a little paraniod about the knuckleheads we elect to government biggrin:
