I believe the presumption is "innocent until proven guilty." So far there is no proof of guilt on Armstrong. The Tour is the last chance to get that proof. No one has ever met the burden of proof- rumors are easy to start, suspicion needs no facts, and allegations do not need to be grounded.

Mcgwire didn't test positive either, the only witness against Mcgwire is a self promoting former player with a new book out. The witness is suspect.

I am not saying that either one of these former athletes were clean, but as we do not have evidence showing otherwise we must give them the benefit of the doubt.
