From the Herald:
Medals are expected to be won in wrestling, archery, taekwondo, judo, swimming, badminton, weightlifting, shooting and gymnastics. Korean athletes have led in these sports since the early 1980s.[my bolding]
Alright, swimming, weightlifting, badminton and gymnastics may not have the same relevance to violence (although the latter sport is preparation for Gymkata!)
I think Pak Tae-hwan could do very well at the Olympics, but saying that Koreans have led in this sport since the '80s is crazy. He races on August 10.
