Of course I can, but it doesn't change the fact, that can really work in case of USA. Also notice that I mostly mean school shootings, and this is the problem for US because if some teen just have the gun in his house, he can just take it. If he wouldnt, what could he do? Take a knife? Sure, but how many people is he able to kill with it, and how many with simplest gun? Also, it would be a little bit harder to get guns for gangs. Im not saying much, harder, just a little bit, but always. And... why would you need gun, if the thief that comes to your house at night dont have it? Won't you deal with one guy with one of your famous American baseball bats? I really think you would, at least stop him till police is comming.
