Here's Tyler Hamilton on last night's 60 Minutes describing in detail the process of doping on the US Postal Service team, as orchestrated by Lance Armstrong.
It pains me to write this, but I don't see how Lance Armstrong wriggles his way out of this. But that's not the cornerstone of what Hamilton is trying to do. Watch the "overtime" clip above and Hamilton makes it clear that he's targeting the culture of doping in the sport -- not Lance alone. I wish they had included that point in the main body of the interview.
(Yes, I indeed noticed the ads by Viagra in the videos. A "performance" enhancing drug. Clever!)
