Well that only goes to show how American sprinting has had a shadow of infamy cast over it and how it has lost it's influence in the 100m event.
Jamaican sprinting on the other hand has risen to it's highest highs and shouldn't really be dragged down with the ship or even but in the same boat as the other offenders.
Although saying that, Tyson Gay has nothing to do with anything wrong about the sport. He has run the race of his life and has set a new national record which he should be proud of. But American sprinting isn't the best in the world anymore.
The way history will remember it is that Bolt won the race by the same margin as he did in Bejing (blowing away the opposition) and that Gay ran a time 0.2 slower then the then world record of 9.69.
I think that this is just Bolt's style, and that he should be praised. I doubt that any such evidence will reveal itself. Something I doubt about other "conspiracies".
