This should be an easy $50 M for Romney to cut. (I made the number up, you get the point.) Many of Armstrongs main rivals failed drug tests. He beat them, and passed the tests. When you create a bureaucracy to police behavior; those overly legalistic 'laws' become the rules of the game and destroy any place for a sense of 'fair play'.
In my opinion Armstrong probably doped, but he followed the rules in place at the time. This is just a waste of time.
