After a 16-year-old Florida boy lost a black belt taekwondo match, he bowed to his opponent, shook his hand ...and then kicked him in the face. The blow knocked his surprised adversary’s front teeth out.
The sore loser was booked on a felony assault charge. The sore winner ended up in the hospital.
National taekwondo organizers are reportedly considering serious sanctions, including banning the suspect from the sport for life.
I think that’s a reasonable response.
Ethics Alarms 
Tae kwon do takes very seriously the issues of personal responsibility and honor. Banning this guy is exactly right; he may have TKD skills, but he sure doesn’t have the requisite self-discipline and respect for others!
It worked for Bruce Lee! Anyone want to bet that the movies were this kid’s inspiration for getting involved in martial arts? After a steady diet of movies and games that stress violence in its most ugly form, kids are naturally forgetful that the real thing is MOCK combat; a sport, not an exercise in bloodletting. But then again, it’s the responsibility of the teachers to instill this realization in the minds of their young pupils as part of their training. Kids, however, forget… and this must be constantly re-enforced.
I would also think that a ban on the members of that school for a certain period of time would be warranted. This was not a beginner’s match. This was a black belt match. Martial arts schools have the responsibility to make sure that anyone they award a black belt to is not just technically capable, but is mature enough. When I was in martial arts, very few schools would allow a minor to test for a black belt on the grounds that they weren’t mature enough. A black belt gives someone the qualifications to independently instruct others (start their own school) if they wish. This person obviously is not mature enough for that. The school has endangered others by awarding this black belt, by instructing this student for this long without requiring maturity in their thought and actions, and by allowing such a person to compete in the tournament. Because of this, I think a sanction on the school is warranted.
Great point, and I agree wholeheartedly. A student that reacts like that is dangerous; this is martial arts teaching malpractice.
