LOL... this is why I carry a knife everywhere I go. If this ever happened to me I'd start of like this guy, all scared and submissive... then stab the guy in the face a couple times.
I think he was hoping to wear him down, Rocky-style, by taking all his best shots, then fighting back when the guy was all tired from beating his ass. This strategy is a poor one!
I'm not one to resort to violence, but if someone hits you, you should just beat the crap out of them. Especially if they are recording. Then smash the camera.
