Please tell me how you know who started the violence.who is to say I am protesting peacefully, get attacked and want to defend myself. Then get shot for being violent.

There is no way this would not be used in some way for bad. You are telling me you want either citizens to pass judgement like that on others who probably don't know what happened in the situation. Or worse, give the government the ability to shoot and kill.more people without reprocussion?
