What Leblanc didn't do was publicly dump on Virenque's record when he retired, nor did he make any comments for the years post 99 that Virenque rode. I don't recall the Tour organizers stating what a relief it was that Virenque had retired, because he was a maggot doper. Their remarks about LA were almost beyond contempt.
And if Leblanc was so upset about doping, (and is so upset about it today that he has to dump on the reigning champion) he should have done more than cash in. The Festina mess was uncovered by French police busts, not by any action by the Tour organizers, and only uncovered because the doping was becoming rather blatant. That makes his statemets doubly hypocritical.
Perhaps the biggest joke in all of this is... not only can they not win their own race, not only can they not properly frame the guy who did, they're not even good opportunists. In a way, this is helpful to LA - if the doping accusations come from people this slimy and gutless, then they are suspect by mere association.
