I think it’s worth pointing out that there’s two parts to this event: the first happened before the recording and it’s when Raxx swung first. This would be the gray area as it’s ambiguous to where the blame would fall- BigT trespassed multiple times but Raxx attacked first by swatting the phone out of T’s hand and threw a punch.
The second event is much more black and white, it’s what we see being recorded. BigTard is told to leave and Cyraxx starts his tough guy talk calling him and his girl a bitch, Tard throws a schoolgirl fit whining he tried to be Raxx’s friend before starting to leave. He then turns around, reminds Chance he got one punch because Raxx hit him first, then goes back up the stairs and asks him if he’d like to go again which is when Chance gets the three combo to sleep town. Self defense is not applicable if you willing put yourself into a position that requires you to defend yourself, the situation was escalating down with just verbal shit talk and Tard went back in an attempt to repair his hurt ego. I don’t see how this part of the altercation can ever be made into a self defense claim
