Oscar Grant, a Black man, lying face down, subdued, surrounded by (apparently white) cops, and with one officer's knee on his neck, was shot in the back and killed. The cop didn't even draw his gun until AFTER Grant was face down with the cop's knee on his neck.
As Kevin says at A Slant Truth:
What the hell did this cop think? That Grant was going to all of the sudden summon his super-human negro strength ala Hancock and suddenly toss the cop with his knee on his neck a good 200 yards and go flying away?
