Did Tyler Cheat?

So the big question is.."Did Tyler cheat?" The facts are clearly stated in today's Velonews post.

"Hamilton is facing up to a two-year ban after a backup test taken at the Vuelta a España confirmed an initial positive test that showed evidence of banned blood transfusions. Hamilton was allowed to keep his Olympic time trial gold medal despite failing an 'A' sample after testers inadvertently placed second 'B' blood samples in a deep freeze, rendering red blood cells unusable for follow-up tests.

Hamilton has vehemently denied he injected someone else's blood into his system and has promised to challenge the validity of the testing method to prove his innocence."

Unless there is foul play or a faulty test, as much as I don't want to, I have to rely on the facts as we know them. His reputation says that he didn't do it, I don't want to believe it and I hope he can clear his name. But for now, I think he did it.

Thoughts?
