Hilariously, an air pistol shooter has been stripped of his two medals for doping. I never gave shooting enough credit as a sport to imagine that performance-enhancing drugs could be a factor.

According to the IOC, the shooter [Kim Jong Su of Korea] tested positive for propranolol, a banned substance used to prevent trembling.

The good news is that they caught him. But it makes you wonder even more about the sports where drugs can really give athletes an edge. Only three athletes have tested positive for drugs so far in Beijing.
