Right.
"The same is true for Tyson Gay. Once a doper, always a doper. Individuals like him have no moral standards and will lie every single time. He confesses only what's known anyway and will not help clean up.
When he comes back, he will continue doping, just be more careful."
With the caveat that he has "low", not "no", moral standards.
There's no question in my mind that he did it intentionally, or with reckless disregard (amounts to the same thing), and that he's been doing it for a long time.
The thing about lying is that you can never again be trusted, you have to prove everything. And proving a negative, like you aren't taking anything illegal, is essentially impossible, ESPECIALLY in the current environment where the only thing that you could use other than your worthless word--official testing results--have been demonstrated to be useless in this capacity, by the fact that he didn't test positive in London, Marion never tested positive, etc.
So he can't be trusted, and he won't be able to prove that he's clean.
Screw Gay. Yes, the others are just as bad, even if they haven't yet been caught, but that doesn't make Gay any better.
As for his "plea bargain", those are supposed to be allowed when the information gained helps in the overall fight. Like someone said before, the suppliers/docs/therapists, whatever, are likely to be beyond the reach of USADA, and so the supply stream that he used is likely to continue unabated, or will find a new distribution channel. Nothing will change in the overall fight, and this bargain will have been improvident. The only thing it will get the administrators is factual confirmation of what everybody with half a brain has known all along, which is worth something if you are an administrator, but worthless to anybody else, and worthless to t&f in particular.
