I called it a witch hunt because there's a specific target, Armstrong. I have no issue with uncovering cheaters, but if EPO was not detectable what's to say that most that ran the races weren't using it, why is Armstrong the only one they constantly mention?
The reason they are going after Armstrong and not the rest of the racers has more to do with the French and politics than it does with catching cheats.
Except the evidence that this is a witch hunt are minimal. The evidence that Lance cheated is strong enough for that. And some of that only goes back to 2010 during his latest comeback so it isn't exaclty old news. If you feel that getting away with cheating for 10 years is fine and not worth digging up that is ok. Frank Shorter for one seemed pretty happy to learn that he was cheated out of a gold medal in 76.
