Nothing like guilty until proven innocent.  I can understand the rationale behind the decision to disallow dopers into Le Tour but it could be presented in a better way by the race director.  If anything I think Christian Prudhomme is doing a greater disservice to the sport by implying that everyone named in the case is guilty by association. 

Certainly anyone that is proven to be doping should be booted from Le Tour and all professional cycling events for life.  As far as the unproven cases it would have been better for Prudhomme and the race officials to quietly pressure each of the teams to have them voluntarily remove those racers, or subject them to daily drug testing.
