Video we found off the net of the Purple belt division at last weekends 2013 NoGi Worlds.
We do not know what went in this guys mind to do such a thing.
He could have hurt or really injured the guy he faced.
Maybe a local that does not care for the cost it incurs to go to and through such an event. Monetary, physically and Psychologically for it to all be gone in a flash by such a terrible and disgraceful opponent.
