If doping is as big a part of the fabric of pro-cycling as many, including me, constantly claim it is, I think an amnesty of sorts is the only way out.
Given a chance, I think most riders would prefer to ride without abusing their bodies (too much). But within pro cycling as riders find it, only the exceptions can get away with it and still keep it as a source of income for you and your family within a sport that operates to different standards.
We can keep banning riders until Kenny Van Hummel gets across the Alps within the time limit, but unless we get to the folk who set these standards, and make sure folk stick to them, nothing will change. Period.
Yes there are "natural" cheats within the peloton. But I firmly believe most dopers are not cheaters by heart, but somehow still end up doping. The doping culture is there, riders have no other option than to deal with it one way or the other, a choice with only downside real-life consequences for both options.
The real culprits are those around the riders that force this doping culture upon the riders. From the shady doctors to corrupt officials to insiders who turn a blind eye.
We need to get people in charge whose sole interest is to keep the sport clean (well, as clean as you can get which is still well up from where we are now). But right now, it is still in the interest of those in charge to keep these folk out of the sport, and retain control.
The only way to get rid of them is to make clean ship once and for all, by shaming them into cold daylight and show how rotten the core of current ship is. Only that way can we get to a whole new set of ground rules, watchmen, and (independent) enforcers. People who have the interest of the sport, races and riders at heart.
The only people who hold the key to a new era are the riders. They are the only ones who can make a case that points away from the riders and towards the culture around them. Without truly damning evidence it will be riders who will keep carrying the can, and the occasional pharmacist.
With entire livelihoods at stake, and only stakes, an amnesty is the only way out, in my mind.
And yes, an amnesty would be hugely unfair on many folk who would have been fingered at the wrong side of the net. But without it, I can't see how we would ever undermine the vested interests enough to change it. Which means that what we keep in place would remain unfair for all, and all the more to the odd rider who keeps being sacrificed as a token gesture.
There is no ideal way out, we are in the mess we are in. But one route is more ideal than the other, I'd argue. It will be "unfair" on riders whichever route we chose out of this mess, so we might as well pick the one that leads to a cleaner future with more safeguards to keep it so, by reinventing the way pro-cycling is governed.
Which leaves us with the conundrum of needing to get an amnesty in place to get to this situation, when the ones who would have to issue the amnesty are the ones with all to lose, and nothing to gain (if my reading of it is right).
Maybe the most lasting US contribution to cycling won't be Lance, but a fed investigation that might penetrate the corruption within the sport. I hope it will. But it will need the co-operation by riders. And I hope the first sheep will make it across the dam for the benefit of all. A damning Fed report might well be their last chance for a few years to do something about the shape of their own workplace.
First we need to show the rot, then we need to start voicing the urgent need for a truth and reconciliation period. Speak and be truthful, and there won't be any consequences beyond the unavoidable. Don't co=operate truthfully then, and you will face full (and even harsher) consequences later.
