BJJ works in Street Fights but this is a bad example....
Shirtless guy might be yelling and ranting but he is going in his car, he looks like one of those guys who wants to intimidate rather than fight and everything works against those guys
BTW it also appears to me that bjj guy is the aggressor, what business does he have standing there by the car. I don't buy this "protecting others..." bullshit when shirtless dude is actually leaving.
