After punch and a kick this guy that obviously have some BJJ training pulled guard on security guard. It’s a pretty weird situation to see in a street fight but he managed to sweep him immediately and get to full mount.
We can’t say if security guard was provoking fight, knowing his buddies will help him, because he was obviously doing something before the fight started but we can’t say what.
But, as stupid as it is to attack the security guard BJJ practitioner got what he deserved.
