I'm really struggling to understand what you're trying to say. Are you suggesting that the results of the doping tests have been tampered with? Or what? I would like to hear more about your theory, as I doubt you have any idea how sample collection works.
Anyway, I think you've watched too many stupid movies. I already mentioned this, but I'm 100% sure that failing a doping test is like failing an IQ test. So I doubt that any kind of secret activity is involving ITA/WADA/UCI employees... Lazy cheaters like Armstrong wouldn't work nowadays,
The UCI could conduct in-house doping tests, as the Americans do, where 90% of athletes compete outside the WADA doping code and even 60% of american Olympic athletes are massively under-tested compared to the rest of the World while being protected by the hardcore gangsters at USADA. Not that anyone cares, right?
But this is Europe, so at least for the sake of the image, independent doping tests are carried out. Is this effective? Probably not. Doping cheaters are always step ahead of the testers.
