Thanks @mineopoly! As always, I enjoy reading your comments :)
I agree, our rights shouldn't infringe on anyone else. Basically I believe you should be able to do whatever you want as long as you aren't hurting anyone else or their property. That would be true freedom. So I don't think carrying a gun or having one at home for protection is infringing on anyone's rights.
As far as the cell phones in schools go, that is a distraction for sure. But I feel there is a way around that. Let kids have them in school, but DO NOT let them turn them on (at least in class). If they misuse it then they loose their right to have one. If an emergency happens then they can turn them on to use them, that way they can be/feel safe as well. Other than that, there is no excuse to have them on.
Your right, no one can control outrageous behaviors, but we shouldn't punish everyone for a few stupid peoples actions.
