Bolt's not clean, I'm someone who ran track in high school and college and follow it year round. I've seen Bolt ever since he started making International competitions. He's not this fast naturally, and it's only a matter of time before he gets caught. The 200 was his best event and he was sucking on Tyson Gay's dust, then all of a sudden he's shattering Michael Johnson's record. Bolt's dirty with a captial D, like this Dirty.
