Officers getting violently pummeled, one has his gun taken from him, shots are fired, an officer is down but, some how, these officers are still able to show enough restraint in handling the situation that they didn't have to resort lethal force until someone was armed and dangerous.
But a "charging" Michael Brown had to be killed, the "brutal" and "violent" Trayvon had to be shot, and "tussling" Walter Scott should've known he would be executed for not following the orders of a cop.
I could go on and on. It's clear that these people see a certain level of humanity in those with white skin that is nonexistent when dealing with black people.
