See what happens when Jiu-Jitsu Falls into the Wrong Hands!!

The Brazilian jiu-jitsu is a great martial art to subdue your opponent and convince them to surrender without hurting them too much.

As we can see in this video this guy broke his opponent’s arm without giving him a chance to surrender. Maybe there was more to this fight that we can see on the video. What do you think, is this a case of the “Excessive self-defence” or was it justified ?
