Notice in the first video, how the boys in the cart are in the same general area as the cameraman? And how it cuts to a scene that's easily 200 yards away?
Yeah, if I were a betting man, I'd put dollars to donuts that the first scene is entirely fake. The second scene looks like it might be genuine, though I'm sure it "conveniently" neglects to show something important right before it cuts over to the beatdown itself, in a sleight-of-hand edit that would make Michael Moore proud. Or at least, it would convince him to have a celebratory cake or two.
Many thanks to eagle-eyed reader Clayton for bringing this to my attention!
