People want to see the world the way they want to instead of the way it is. I have a simple question: If the US is returning to the days of the Wild West era where everyone carried a gun, what were the rules of engagement back then? I mean, under what circumstances was it ok to pull out your gun and kill someone (or badly injure them) in self-defense? What if someone offended your wife? Called you an obscene name? The reason I ask is because I think we are heading in that direction and I wonder how our laws will need to change to accommodate everyone carrying a gun. I am both a practical man and an idealist. Ideally, no one should own guns and we should all settle disputes reasonably. Or if we are in great pain, we should not feel so alone that we act out against others and instead seek their comfort and friendship. Further as a society we should not shame people for being depressed or having an illness. But that is not the way the current world works. I was thinking then, is the answer that the faculty at schools carry side arms? If that were the case, this tragedy would have probably been on a much smaller scale. Not ideal, but it may be practical.
