To Ghost: the reason no one could sue Eddy to get the prize money he stole back is that his positive test only proved that he was doping on that exact day. Anything he won after that could easily be sued over, anything before that...as long as he insists that they caught him on his first injection ever, there's no proof to show otherwise.
But now that he's admitted to a 3 year period of doping, we can see that he stole thousands of dollars. Regardless of what is possible within the US court system, there is no denying the fact that he is a criminal who is still, to this day, enjoying the fruits of his crimes. He is not apologizing, or paying back the stolen money. He is asking for some kind of redemption without ever making restitution. It's sick. The only reason he's saying it was a mistake now (if he even did?) is that he got caught. That's what he regrets - the consequences of getting caught, and the worst part is he got to keep every single stolen penny!
