Over my 34+ years involved in professional sports, from the IOC to national organizations, I have been involved in directing numerous investigations concerning cheating and doping. If there's one thing I've learned over this period, it's that, even if it takes years, cheaters almost always get caught eventually. In the case of the Olympic Games - cheaters caught after the fact can and will even have their medals retroactively stripped from them. It isn't worth it!
