Welcome to the slap heard around the world! I am in no way condoning hitting a woman, but this chick kind of had it coming. She was really trying to provoke a fight from someone. Finally, this dude had enough and unleashed a slap heard three trains away.
This is just straight up temper. This cop wants to search a vehicle, the kid declines, and the cop smacks him upside the head. Now, I usually all about people getting smacked in the head if they deserve it, but this seemed like a bit much.
