The United States murder rate has dropped more than 50% since 1992. It seems to be getting there, with or without increased gun control.
I've yet to determine the cause, however, so make of it what you will.
@kelario: At first I thought you were being sarcastic, but you seem to be serious. Hm.
First off, you can't compare the USA and Canada by weapon laws alone. It's also a fact that Canadians are much more nicer than the usual American, since in America you have a elbow society. I would prefer to use a much more insulting term, but hey, rules and stuff.
Fun question: Who is the bigger criminal? The guy who shoots you or the society that drove him to that point?
I hope that wasn't too much sarcasm to understand. I would like to conclude my post with the following thesis:
Guns are made to kill (not to "defend", you got tasers and stuff for that), so there would be less gun murders in America if there would be less people ready to kill for little reasons. So the problem isn't the gun law but the people. In America.
But as always, making it more difficult to get guns, would prevent many kills in affect I bet.
I also wanted to make a mockery of how tools of death and "Love and Tolerance" fit together, but I have a meeting now, see you later!
