not really a street fight
Here is a perfect example of how useful and peacful Jiu-Jitsu is. The BJJ fighter who is defending himself after the man he is controling tried to rob him is camly explaning to the people around him the situation and explains he is not going to kill him or even choke him unconcious. He is going to stay in back controle with the rear naked choke locked in untill the police can arrive.
