I listened to the BBC radio interview with Armstrong's colleagues in the US Postal team, and from all the evidence and accounts, it showed that those who didn't dope were singled out in the 'cycling society' and portrayed in a way that they were wrong for not doping.
Also it was said that there was so few that didn't dope, that in one particular race (i can't remember which) if the title was given to the first person who was not using performance enhancers/EPO/Blood doping, it would be given to the rider that came 23rd.
Its just one big scam, and the majority of races are just completely illegitimate
But i would say Lance himself is one of the main culprits due to the level of his involvement
