A teacher got sacked for 'grave misconduct' (recent case) for holding a teenage boy by the arms to get him out of the classroom, as he'd been attacking other students. This PC whacked an innocent man going home from his work and laid him flat, indirectly causing his death. He should stand trial for assault and ABH, and (naturally) lose his job. He can't possibly continue as a PC, he's a violent chap not in control of himself.
