To Americans who keep repeating the unbearable "guns don't kill people", I say: "neither do atomic bombs", so why not let Iran have some? Not a nice thought, eh? Items that go around will get used, and in the worst way possible. It should be super hard to get your hands on one, period.
It's also silly to base the right to wear arms on that old piece of paper. It's nice to stick to the good parts, freedom etc. but if the constitution said the earth was flat, you'd also still go with that? Also silly.

I don't even wanna get into it all that much, because it's none of my business but the arguments portrayed (not necessarily in this thread) are sometimes beyond comprehension.
Especially the stance "if only every victim in the theater had a gun to fire back" makes me shake my head. What is this, the fucking Wild West?

It's a vicious circle. Burglars wear guns because they expect the house owner to have one. And the house owner gets better guns because he knows the burglar will bring one. It can only get uglier from there. Of course there is hardly a way back from this situation.

Beyond hunting or sports I don't see why anyone should have a gun beyond a regular 6-barrel one. Certainly none that can shoot dozens of people within seconds. But since it seems to insult certain people just to think that way, the best one could hope for are more restrictions, tests and waiting periods.
