Piccolo's case is complicated. Vaughters deserves applause for ratting him out to the UCI/ITA when it was just sleeping pills (though we should also ask why he ratted him out when it was 'just' sleeping pills).
But...
But does Vaughters deserve to get a hall pass when he says "riders of today don't deserve the burden of" the past? That's the burden of men like Vaughters who lied and lied and lied about doping. Men like Millar, like Hamilton, like Landis. They are the people who burdened the riders of today.
