The sport of Taekwondo has long been marred by controversy, but a controversial disqualification at the Asian Games looks like it will result in a case at the Court of Arbitration for Sport and may well be the straw that broke the camel's back in regards to future Olympic status for the sport.
Taiwanese fighter, and gold medal contender, Yang Shu-chen was ahead of her Vietnamese opponent (a woman who eventually won a bronze medal) 9-0 with 12 seconds remaining in the first round when, inexplicably, Yang was disqualified. Video CLEARLY shows that the sensors that she was alleged to have used were removed from her socks upon the request of the referee prior to the start of the match. Said sensors remained at the side of Yang's coach for the entire match. With 12 seconds remaining, a Korean technical official examined her heels and found no added sensors. He then called the match referee (a Filipino) to bring over the sensors that had been on the floor since the beginning of the match. He then examined them with a fellow Chinese technical official and after a closed-door discussion, disqualified Yang with no explanation to the Taiwanese delegation in Guangzhou.
This is as dispicable as the 1972 gold medal basketball game. The entire country of Taiwan is up in arms, with Korean and Chinese flag burnings and (sadly) racist remarks against people of the two countries.
The site below does as good as job as any of explaining the controversy with a 14-minute clip showing clearly that Yang was clearly unfairly disqualified and cheated by the Korean and Chinese technical officials.
