The 60 Mins piece is mainly about Tyler Hamilton and what he claims to know and claims to have seen. Which is Armstrong taking PED's and encouraging others on the USPS team to do so. This is the same Hamilton that cheated for years, denied it for years and was caught. And...what didn't seem to make the telecast last night...he's looking for a publisher for his upcoming book. So this guy's less than stable, Landis was less than stable and last night's Hincapie angle was really, really weak IMO.
I suspect LA took PEDs and participated in blood doping. But if the best the prosecution can do is come up with Hamilton/Landis type witnesses, the Armstrong empire should be fine.
