The only odd thing about this is the TDF stated before the tour started that if a rider was caught doping the team was gone. Now it has happened twice and the teams are still riding. Empty threats?
As far as spanish cycling not getting it. Until teams start to test themselves like slipstream, there will always be questions and you leave the rider up to test his own moral fortitude. If you don't know about slipstreams doping policy, their riders are tested every 14 days by the team (this does not include random wada or uci testing nor individual race testing), once they have a baseline for the riders chemical composition, it doesn't even matter if they test positive for a performance enhancer. If their levels are off, then the rider has a problem.

When teams are willing to adopt this, I believe we can be assured the riders are clean.
