So the guy in the three second video is supposedly a security guard attached to the players. Best guess at the context is that he was diffusing something or possibly challenging the guy with the camera to do something, hence the response of "I will".
I'd say this is a mountain being made of a mole hill. I tend to think the Crusaders players (there is no denial they were involved) might have done something a little immature and it's been seized upon and blown into an incident by the affected.
