I saw Bob Costas, longtime host of the Olympics in the US, being interviewed and he explained why US cheating is different from when Russia or China cheats. It's because individuals in the US choose to cheat while in Russia and China it's state sponsored. Nevermind that most cheating methods start in the US under the guise of sports medicine are not considered cheats until it's discovered and there's a test for it. By then a new cheating method is created. That's why athletes from countries that get caught cheating are using older methods passed down hence why they get caught. It's not surprising that a good portion of US athletes are the sons and daughters of the rich hence why they get access to the latest and undiscovered cheats as the US brags it has the best sports medicine program in the world. And they know this is happening because it's only recently sporting authorities started keeping blood samples of athletes instead of immediately disposing them after they've been tested. In the future they will be able to test old samples for cheats that weren't known about at that time. A US institution that creates cheats is at least as bad as state sponsored cheating.
