You're one blind racist for sure. If you saw the video you would have seen the white guy harassing the black girl with kids in the car. Then the Black guy comes out, and shoves the punk away from the car, and he stumbles, and falls. Then a third guy comes out of the store. The Black guy turns to be sure he is not a threat. As he is turned away the punk draws his gun, and shoots the Black guy as he is turning back.
Plain and simple murder, and if the Prosecutor has any integrity he will find that third guy.
