I see this as "defender hits QB in face after play" That's how the NFL sees it, not who was involved. Rapist or no rapist, douche ex-pat or no douche ex-pat. I think 25,000 is too little an amount when he fully intended to do that. James Harrison fully intended to use his helmet, he got a bigger fine. Seymour fully intended to attack someone after a play was over, he should get the same penalty.
Launching yourself head first into another player's head can kill or paralyze him. Hitting a rapist in the facemask with an open hand will only cause the rapist to fall to the ground and act like a soccer player.
