There is no evidence that shows we're any less safe because we're not allowed to wander the streets tooled up. Would you consider the streets of inner city London safer than the mean streets of LA? Would you feel safer walking through gangland with a gun, knowing everyone else, including that group of angry-looking men on the corner, might be equally armed?
I'd rather live in a country that makes it very, very difficult for a junkie with no fear of death to get a gun.
