Marxist_fixie, you're confusing two things here--evidence and court convictions. It is true that none of these riders were convicted of doping in a court of law, but there is abundant evidence that they doped. Numerous experts and witnesses, e.g. riders who doped themselves, have said so. Yes, if there's no court conviction, you can't technically maintain it in public, yada, yada, but the evidence is there, e.g. how speeds in the pro peloton suddenly went through the roof in the early 90s. Do search for it--it's not that hard to find. (NB this is a discussion that we've all been through multiple times. You'll find quite a few links and detail in the Lance Armstrong thread, as hippy mentioned.)
