As Noodley has said, the system is stacked in the favour of the dopers. Hard evidence of doping (other than an admission) would be a positive test. In this years tour, Rico tested positive (I read somewhere but - can't remember where, that later he stated he should have tested positve on occaisions prior to this), then Piepoli (from what I've read) admits to using the same substance but as far as I know didn't actually test positive.
In other words, the testing system is not 100%. It's quite right to be suspicious af any rider who is somehow involved with Fuentas.
