One does wonder when the statute of limitations is going to run out on the accusations against Armstrong. Regardless of whether the situation now is the result of him being particularly clever at hiding drug use, or the result of bungled testing by the various committees, at this point it seems pretty unlikely that they are going to get any convincing evidence. This latest setup does have a particularly strong smell of bogosity.

Five cyclists--Jonathan Vaughters, George Hincapie, Levi Leipheimer, David Zabriskie, and Christian Vande Velde--received the suspensions after acknowledging they had engaged in doping and agreeing to testify against Armstrong. Under the reported arrangement, the five, and perhaps others, would be able to compete in this year's Tour de France and potentially another major competition before the season ends...

...when they will then testify against Armstrong.
