I'm not big on cycling, but aren't the athletes tested for drugs before/during/after the race? Is so, why wasn't anything detected - and more importantly, reported - any time during Armstrong's last seven victories? It seems odd to report it only now. And yes, I understand that there were allegations before, but was there ever any documented proof? And if there was proof, why was Armstrong (or anyone else who doped) allowed to race in the first place?
