Floyd Landis - further allegations

I know someone who's had this conversation with Vaughters. His view best summarised as mutually assured self destruction, if he does come clean then LA will come gunning for him and his team. He doesn't want that.

Just to get this right, you know some one who has had a conversation with Vaughters in which he personally implicated LA in doping but will not out it for fear of his team/ career??
