Do tell! My guess is that years of anger/frustration/dislike, etc finally came to boil. Little guy(who's displayed anger multiple times on CC and other SM sights) runs over to intervene(butt in) in a heated discussion between the larger alleged aggressor and a new rep and gets into personal space of said alleged aggressor. Both most likely imbibing and not exactly thinking their most clear. Big guy pushes little guy(who's possibly a little off balance anyway due to alleged imbibing) stumbles, falls and gets hurt. This is just a theory of possible events.
