Violence is a problem of inequality. The bottom 90% fighting over a smaller and smaller piece of the pie. That's where the problem is and the solution needs to address that. What I can own has no bearing on anything. I don't see kids gunned down in America as any more or less tragic then kids starving or dying from preventable disease or car accidents. Dead is dead and they are all tragic. Unless we want to live under a complete police state where we are not allowed to leave our homes we are going to have tragedy.
No government around the world has moral authority over anyone. They commit wholesale mass murder on a regular basis. Hell they paid for my college and paid to send me around the world to do it. So they are not going to tell me what the best way to defend my family is going to be. I will decide that on my own. When they clean up their act maybe they can have some input.
