Lance Armstrong stripped of Tour de France titles and banned.

[Tiberius]

All I've heard is that the "evidence" is witness testimony. Armstrong claims that the witnesses were coerced into testifying by corrupt officials. It may sound like a long shot or a conspiracy, but the real question should be, how has he passed every single drug test if he'd been doping? Physical evidence > witness testimony almost every single time, and all the physical evidence seems to support Armstrong.
