Long time lurker, second time posting... I think. But, from my awesome ability to watch the video. It looks, to me, that the camera guy was more concerned with getting a short clip of Carl, and not watch where he was walking, then accidentally bumped into the A&M guy with the visor. Lost his balance and dropped his camera. It makes sense to me, since when you fall you try to catch yourself with your hands to brace your fall. I think Carl might have seen out of the corner of his eye, or heard, and tried to help him. But with this video and no sound nothing can be confirmed.
