I can't speak for everyone but as an American I am ashamed that this was done because it has sullied the reputation in the single greatest sporting event in the world. And that's a damned shame.
As an aside I see that Jan Ullrich evidently was up to his ears in doping. But he didn't ride the Tour.
I think the only thing that can possibly change this is a lifetime ban for the first offense.
I was reading "Sports Illustrated" today and Cadel Evans account of Landis's accomplishments in Stage 17 was completely unbelievable. You might want to read it. It was written before the positive test.
My $0.02.
Yes, we perfectly know for years that some riders' accomplishments are far above the maximum physical human capacities, even if you have a gift and if you train a lot. And Armstrong was familiar with this kind of "miracle", especially in some mountain stages or against-the-clock stages. That's why he's suspected of doping. But no evidences, no doping, isn't it ?
