I can't see a cop risking turning his life into a living hell of paperwork and inquests and disciplinary hearings just to shoot a guy who was doing nothing wrong in the back.

The officer must have felt threatened to pull his sidearm in the first place, surely? Was he trying to flee the scene?

We need to replace the text on this so everybody knows that "he dindu nuffin, he a good boy."
