The proof is in the test. Mourhit (4th fastest ever), Sief (7th fastest ever), Bauman (12th fastest ever). 3 of the top 12 have now been nabbed... or 25%. I don't want to point unfounded fingers, but you have to think that Lahlafi was on something too... Mourhit's buddy and training mate. I was always a big believer in Komen not being on anything, but I wonder now. Geb and Tergat I still believe were free of anything illegal, but who knows. 1/4 of sub 12:54.71s are drug enhanced, which makes me think, most probably are. Also, think about how stupid you have to be to be caught. It wouldn't surprise me if 75% beat the testers, meaning all are guilty of cheating.
