Slander? Doping?

Rumour has it, the American winner of Le Tour de France, Floyd Landis, is caught being yet another bicyclist taking performance-enhancing drugs. The test positive for drugs is said to have been taken during Le Tour. Mum (who is American, in case you have not read much of my blog before) says she does not believe this, she says American athletes never have to take drugs to be the best. Landis has disappeared, he did not show up for competitions in the Netherlands yesterday and Denmark today. Is the rumour just slander? I am not so sure. Too bad if it is true, for bicycling, Landis, and America.
