Did I say you could not have firearms? I have been talking about revolvers/pistols/automatic rifles/assault weapons. I advocate that those should be limited to people who use them in their work (law enforcement, military etc.) and to those who use them actively for sports.
I said this in another thread. I've never shot anyone, or even shot at anyone. So that leaves me with hunting, and sport, (I'm not military or a policeman), both of which I do, and which I bet close to 100% of lawfull gun owners do as well. I couldn't find any numbers on it, but I can think of one instance where a person with a CCW permit shot someone in a criminal fashion. Even then, he wasn't legal because he had been drinking. In Minnesota our permits are no longer valid if you have alcohol in your system. I don't remember if it was zero, or a just a really low number.
