"WOW! the comment you make is almost with a child like mind. Not saying bolt and Blake are clean, but they did not test positive, so therefore, nothing to report. Stop acting like they are just targeting Tyson Gay and letting the rest go. You are acting like Bolt have some influence on the IAAF and WADA so he is dirty but they are letting him off the hook. If anything, I would think they would favour Tyson Gay, since U. S. A have more influence that most other country (case and point, Ben Johnson got caught yet Carl Lewis got away). Many Jamaicans have gotten caught, so they are not unfairly targeting the American sprinters so stop crying like a little bitch! when you all were getting away with it for so many year when the U. S were dominating yet nobody said anything. So you feel that Gay is respectable so he does not deserve to get caught, is that what you are saying? so bolt and Blake are not respectable or any other athlete for that matter? Don't get me wrong, I like Tyson Gay, but it could be said that if he was respectable, he would not cheat."

One of Two possibilities -
His comment suggests that he in fact did know what he was doing but that he was trusting some individual(s) to guarantee it would remain secret and safely hidden - a financial arrangement! If he were actually innocent here, you would think that he would be on his soap box right now screaming like crazy - "There has been a mistake and I'm gonna sue the $hit out of you MF'ers!" Yea, he's a gentleman alright and has always kept his head down and his ego in check! Somebody on the inside goofed though and failed to keep their end of the bargain.
This "Somebody", one of his "parasite managers" or "close physical trainers" has been put up to slipping PED's in his drinks to get him secretly juiced up and just expecting Tyson to go along with it and not question "What's in this or why should I have to eat this?" I'm certain the answer is the same for all of these top guys - "You wanna be the best right? Well then, shut the fu∆k up and trust me!" The money that he makes get split between them - the more he runs the more they get - the faster he goes, the more he wins, the richer they get! He's their tool and a lot of these scumbags who get near these guys at the top play their game stealthfully as to avoid being directly linked to any administering of the drugs themselves. He trusted somebody alright but that somebody was either threatened or blackmailed himself or simply got careless. Or, they had a huge falling out and Tyson refused to go along with the game any longer, so they punished him!
or like Gatlin he did with full knowledge and just took his chances with the rounds of testing.
Remember, "taking samples" doesn't mean they test all those samples!
