We guess the world has gone entirely batshit, because within the past few weeks a some of the craziest mass transit fight videos we've ever seen have hit the web. First there was the baby carriage and mace brawl, and now there's this.

Literally unbelievable, this video captures a squad of armed dudes rolling up on a bus in Philadelphia with pistols and an AK to shoot a guy that criticized a woman for hitting her child. The woman called the baby's uncle, who showed up with four of his boys, everyone of them strapped.

Just add doves and you've got a scene from a John Woo movie. Watch.
