The IAAF or IOC or both stated that their was no intention on the part of CO to enhance her performances by ingesting owt; she was administratively stupid and paid the price.No evidence was ever presented to the contrary , a somewhat different case with Merritt.
It never ceases to surprise me that fans on this Forum can so frequently always find an excuse, what is referred to as mitigating circumstances, for their own athletes breaking the rules, however onerous; and when a WC or OG comes around with a potential medallist on the rack the USA Track authorities have in the past been a bit lenient.
For example,just noticed ,what I did not know, that a certain woman won a silver at the OG in the 100m hurdles in 1992 but she was not disallowed to compete at the American OT, conveniently. So says Wallechinsky in his book.
Lets hope that the IOC and WADA can get their act together and impose bans to discourage cheating or breaking the regulations by the next OG in Roi.
