But if one wants to be cynical, he can say that the test results were fabricated or the blood sample was processed first, or USOC bribed the test examiners, then you will have no way to prove Phelps' innocence, will you?
I don't question Phelps. I am just saying if one goes on the cynical path as some posters did, everything is up to question and there is no much one can do to prove anything one way or the other.
That would be an accurate parallel if there was some evidence that suggested Phelps used steroids. However there isn't that I'm aware of. That being said, I would suspect there are a great number of people in the world who will suspect that he's juiced.
I wouldn't question the age of the Chinese girls purely based on looks and past history. It's looks + history + evidence + covering up of evidence that makes the case.
