Bumhunting?!

i was watching 60 minutes on sunday (the football game was late, so 60 minutes was late, so the amazing race was late and i was waiting for the amazing race to come on) and they did a special on bum hunting. apparently it is the new "activity" sweeping high schools.
the main goal of bum hunting is to kick the crap out of a homeless person, generally using either a metal pipe or a baseball bat. if you can't find one of those things, just plain kicking the bum is good enough.
apparently this "activity" was originally devised by a bunch of buys producing a series of movies call "bumfights". this series of movies has sold over 300,000 copies. in the movies, guys offer homeless men alcohol or a few dollars to do Jackass like stunts, which look terribly painful and dangerous. in a few "skits" (as the producer likes to call them), the guys sneak up on a sleeping homeless person (who has no idea he's part of this movie), bounds and gags him with duct tape, and beats him. "skit"? how about assault?
the story focused on 4 teenage boys who had been arrested and put in jail for most of their adult lives for killing a homeless man who had the misfortune of stumbling on them smoking pot in the woods. they beat him with a metal pipe, a piece of wood with a nail in it, and their bare hands. the poor guy died. when asked by the host why they did it, the kid responded "for fun". the boys' favorite activity was to watch the "bumfight" movies. the kid wanted to let other kids know that even though they might be beating homeless men for fun, they shouldn't cause they'd go to jail. not because it's wrong, but because they'd get in trouble.
i think this is one of the most disturbing things i have heard in a long long time. movies about beating homeless people and feeding on their addictions and situations. kids beating anyone, "for fun". and the worst part, these stupid movies have sold hundreds of thousands of copies. and we wonder why the world is in the state it is.
