Imagine a black community that largely feels (and by data proven to be) oppressed. Now that community has one of its children murdered by the police. When they want to take a stand they are confronted by a wall of heavily armed police that look like they could be fighting a war in Iraq (but as many have said they're even better armed).
What possible reaction do you envision the black community having? I applaud them for keeping their composure as well as they have. I could not do that.
