If you were not too scared to watch the video and poison your mind then you would have answers to these questions
In the vid he says (paraphrasing )he tried to defuse the situation at least 10 times, continently walking backwards trying to keep him at arms length. The bloke kept coming at him.
He could see that there were at least 2 security there and members of the public - the bloke seemed to be in good hands
He contacted the police straight away left them a message - he played the recording of it in the vid
He didn’t relax he said he was shi-tting himself
He says that if he had stayed then within minutes there would muslim gang lads there and his life would be in danger.
He says he was really scared that there would be no CCTV of the section before the punch but was really relieved when the police showed him it as he says it completely shows self defence.
I think I caught him intimating that he has his own video of the whole thing from his phone.
He was also expressing remorse for the chap and not blaming him as he has been brainwashed by the media about him.
