Why is it that cheats think that if they have a clean performance, then all past cheating is cleared? No matter what Kip does in the future, he will always be judged by his past disqualifications and fabricated races.
It's the same story as the UK cheat, who hopped a bus to the finish of his race. Although he is capable of running the posted time (as he proved in a subsequent treadmill run in front of a camera), it doesn't absolve him of his cheating on that day and continued denial of his cheating.
Why is it that neither is able to step up, admit his mistakes, promise to change and put an end to the controversy. It's the pathological element that keeps the conversation going.
