Funny thing with all these dopers and WADA... if you were to hand over all the data to someone like Victor Conte... he could point out who IS doping, who is NOT, who to target, when and how immediately by looking at the before and after (bio-passports) and avoid having to waste and immense sum of money on wasteful testing.
The biggest hurdle for WADA is that the majority of tests draw blanks even with people they KNOW for a fact are doping. And to accomplish their goal they, sometimes, even have to resort to iffy "tactics" to get an athlete to concede. Take, for example, Alberto Contador. He was busted for 50 pictograms of clenbuterol. 50 pictograms of clenbuterol is not doping. Alberto chose not to take the case to the ordinary courts but, had he, he would've most likely won the case and forced WADA into including specific, scientifically-backed data, behind their contracts. And WADA, I suspect fearing that they were exposing themselves to a huge case, leaked the now famous story of the plasticizers. It was a clear case of intimidation, and Alberto lost because he wimped out, but he certainly had the ability to bring WADA to its knees.
