So we should believe what, that Armstrong is really from the planet Krypton, since he was able to beat all the cheaters without doping? If the cheaters admit they cheated, and Armstrong beat them, then it’s almost redundant to get the cheater’s testimony against him. He’s already testified against himself just by winning in such a playing field.
OTOH - we all, unfortunately, live in a seriously messed up world. b. Being better than others means a person must have cheated? I have no idea whether or not Armstrong cheated. I was only pointing out that international sports organizations operate as much on innuendo as facts. In many cases, their PR status is more important to them than the athletes that make them possible. Follow the money.
