"So, if you are well aware of state sponsored doping, why are you giving Jarmila's record credibility?"
Because I am a realist, and to pick out one person because they came from a certain country at a certain time is simply lazy, and ignores the fact that doping has existed across race and country for decades.
Carl Lewis was the "golden boy" of US athletics, he could do no wrong, except he could because he was a doper.
In 2003, Wade Exum the USOC director of drug control from 1991 to 2000, gave copies of documents to Sports Illustrated, that revealed some 100 US athletes failed drug tests from 1988 to 2000, arguing they should have been prevented from competing at the Olympics, but were cleared to compete.

I do not give anyone credibility, I just point out the hypocrisy of sport and different countries approach to doping.
