Well, I think they might have been. After all, they have an accident but theres no witnesses or signs of it on the road and all they have a few scrapes and bruises?Come on. And they wanted a drug test done in the hospital...
Why did they drop out? So that the Olympic committee couldn't do anything to them, thats why. But there's enough evidence for they to be brought up in front of the International atheletics comittee and they could ban them for 2 years.
