As someone who has trained in traditional martial arts for 10+ years, this makes my jaw drop in astonishment and rage:
"A mentally ill homeless man wanders into a dojo and makes a bit of trouble. Instead of doing the decent thing and handling this situation with tact and intelligence, Bobby Joe Blythe allows his shihan to beat the man, and then deposits him in a dumpster."
Even if he was 'dojo crashing', this goes too far. Even if 'touched in the head' a bit, he remains respectful and non-agressive, and I'd say is the only real martial artists in the video (even if he's never had any formal training!)
Everyone else should have their rank and association abolished.
