Really?
Take a good look at Chicago... a very anti-gun city. Take a good look at the crime stats there. Compare those stats to say, Utah, Arkansas, ARizona, or any other state that doesn't make law-abiding citizens unable to defend themselves.
All these regulations do is make it easier for the criminals, who will get guns anyway, to perpetrate their crimes on innocent people. Fear of someone fighting back, with lethal ability, will deter more crime than cause it.
