Call me naieve but I don't think Lance is guilty. The organization that is investigating him is a private organization though powerful and influential. There is a large contingent of butthurt teams, their allies and influential figures that have a vested interest in seeing Lance's TdF wins struck, teams that were found guilty of doping etc themselves, or lost to him. I can understand that Lance would grow weary of fighting, despite countless vindications. I hope somebody takes up his cause on his behalf.
