It's interesting that, so far at least, posters seem quite happy to defend Aden. In the modern sporting world, when you coach a stable of runners who are beating (and in Dibaba's case, absolutely stomping) the times of high-profile dopers of the past, it seems to me that that would arouse a little suspicion. What the truth is is anybody's guess at this point. But simply dismissing someone because they are a known doper is silly. Everybody lies at some point in their lives, but we can't dismiss everything we hear out out of hand merely because it comes from known liars.
