It's in the forums rules that you agree to when you sign up. Contrary to most of this thread, you can intelligently discuss this topic without a tirade of profane misspelled words and posting links to RWNJ news "sources". This sucks, kids do stupid things. Do any of them deserve to be shot and killed over it by a citizen with a gun? absolutely not. Responding to violence with even more excessive violence is not the answer to this. The reason things like this happen is the poor mental health care we have in this country, and the ever growing income inequality gap.
It's not about responding with excessive violence. It's about protecting yourself. We call those that don't protect themselves sheep.
