I'll try to keep the responses short, but at the same time, address three of your posts.
Does Kenyan corruption infiltrate as far as the CAS in Switzerland? Last month, the CAS remarked that the source of Kenyan Rita Jeptoo's EPO was undisputedly a local Kenyan doctor, and observed that these visits to the local doctor were kept hidden from her coach (Berardelli) and manager (Rosa). While we cannot rule out Kenyan corruption, or plain old incompetence, it's possible Kenyan prosecutors dropped the case against Rosa because the prosecution had no case.
We should do this because of all the positives that have come out since?
Balakhnichev's email says it started for Russia in 2011, under the threat of losing the 2013 World Championship, and it ultimately didn't work, thanks in part to constant internal pressure from IAAF staff like Thomas Capdevielle and Huw Roberts, wanting the Russian positives cases followed up.
As big as this scandal is, the only evidence points to this being something setup between Diack and Russia (then followed by Turkish athletes, and maybe Morocco?), during 2011 to 2013, and the attempted extortions started unraveling from within almost as soon as the first delayed sanction. For example, despite feeble attempts from Seppelt to implicate Kenya at the time, there is nothing to indicate the IAAF colluded with any East African nation, or any Dutch or Italian coaches/managers.
Well he did say he partnered with Le Monde, but courage to publish what? Much of what Seppelt wrote we had already learned from the IAAF Ethics Commission one year ago. What is new? We knew how much Shobukhova paid, but not the others. Now we learned it was about the same. And now we have an email from Balakhnichev that top IAAF officials would be implicated and go down with ARAF. Oh, we already knew that top IAAF officials were involved, from the IAAF Ethics Commission report and three lifetime bans, and a 5 year ban. What more did Seppelt tell us? Granted, the Ethics Commission investigation was limited in scope to what was in the complaint, by their own rules, and had no authority to compel witnesses, so it's possible that the French criminal investigation finds more, for example, against Dolle (where French police found a lot of money at his home).
