Lance Armstrong Investigation Dropped
• ESPNThe Armstrong case had its genesis in doping allegations. But because sports doping is not in and of itself a federal crime, the case would have been built around fraud, conspiracy and other charges related to the violation of his team's contract wit



I like The Agitator's take on this (which is where I found the link to this story) story:
Feds end criminal investigation of Lance Armstrong, but “sources close to the investigation” continue to smear him in the press, anyway. Don’t hold your breath waiting for a criminal investigation into who is leaking grand jury testimony.
