That may be true. All I know is that when I lived in Louisiana, where a HUGE porportion of the population is armed, the crime of "home invasion" was unkown. Yes, accidents are a problem, and frankly, I think people who are so careless with their guns as to allow untrained kids access should be punished accordingly. But crime? I hate trotting out the old cliches, but criminals aren't actually going to say "darn, we have to turn in our guns now" if they are outlawed, are they?
(For honesty's sake, I should point out that, while in past discussions on this board about gun control I made note of the fact that I didn't own a gun; that is no longer the case as I own a 9mm handgun. Only take it out to go to the pistol range. I can't say it would do me any good for self defense since, if anyone broke in, I'd have to find the key to the safe, figure out the combination, load the damn thing and THEN tell the robber "okay; I'm ready now" before it would help. Just have it because I tried target shooting and liked it. Oh, and to shoot gun control advocates, of course...)
