Question - how is this thug any different from every other thug? He hit a guy and the guy died as a result? It's happened before. I think there's too much emphasis on "martial arts" in this article. It should've been called something less sensational like "old man attacked and killed," blaming the creep that did the crime rather than portray him as a monster for being a martial arts enthusiast.
well yeah, we all know it has little to do with him being a martial artist, i think we all just went off on a tangant about how much of a role model a instructor is.
Yeah, i read that once before. To answer, we don't know if he had trained under anyone specifically or on his own. To sum it up, anything can be misused, abused, profiteered, and out of the moral concept.
