I don't mean to ruin the joke but the cop has like no pieces left. He looks like he is getting beaten. I don't know. It's kind of hard to tell from this far away.
Also, the black man may also be another cop wearing a windbreaker. Same type of boots, plus they are behind a barrier, plus you cant quite tell if he is wearing a gunbelt or not.
Do I really need to mention the king anyway? The guy was on the other side of the board, like two moves from being checkmated. He wasn't really involved in my checkmate though.
