I find this discussion weird. On the one hand, we all complain that too many dopers beat the tests. There is a belief among many in this forum that the UCI contributes to this by protecting certain riders, by giving them advance notice of tests, dismissing positives secretly, or whatever.
But now, when a test apparently catches someone, a lot of people are accusing the UCI of nailing an innocent rider. WTF?
The passport is not perfect, but neither is any test for a particular PES. As with the latter tests, the passport is designed to let a lot of dopers slide through, in order to minimize false positives. In the almost once in a blue moon situation when someone fails the passport test, I think it's a pretty good bet that that rider was doping (Actually, we could just throw darts at a board with riders' names on it, and any hit would almost certainly be a doper, but that's another story).
Pellizotti is *****ing for the same reason Tyler did, Heras did, Vino did, Floyd did, etc. Not because he's innocent (he might be, but I doubt it), but because he has been caught while a lot of equally dirty riders were not. That's a shame, but getting cleared is not going to contribute anything to making the system better. On the contrary, if anything it will force UCI to raise the bar to the point where virtually every doper will pass.
