Casey's had enough. The bigger kid on the right "has been bullied his whole school life," says the video description, "and this is what happens when he snaps!!" Hence the jackknife powerbomb. The Facebook commenters are universally in his corner, as we all should be, but the school didn't see it that way: Casey was the one suspended. Free Casey!

UPDATE: The school's actions against the students and the world's reactions to the video.

UPDATE: The bully apologizes — sort of.
