So to be fair to the cop she did strike him first, it's hard to see but if you looked closely it's there. Still there was absolutely no call for his own violence, he should have arrested her since she did in fact assault a police officer but he was in absolutely no real danger, he let his anger get the best of him and... well, literally knocks her on her ass with a haymaker. Really Cop? Really? Was that really the best possible decision you could've made as a member of law enforcement?
