Why not go back and test other athletes' samples? What about, say, the winners of the French Open from 1999 or other years? Or, even better, why not test the winners of the 1998 World Cup, which was held in France. Surely those samples are still available, no?
Maybe anti-Americanism isn't the motivation for this move against Armstrong, but until I read that L'Équipe is investigating some other big name, non-American athlete I'll remain suspicious.
