That's just it. All what golds? I looked at a few Championship years, and if you take away race-walking, I see only a handful of middle distance women runners, and virtually no men. For so many "suspicious" profiles (more than 6x the next country, and about 14x the USA), they don't seem to be significantly overrepresented on the podiums, for a country of their size, and for the men, they are virtually non-existant, with the sole exception of race-walking. And some of the golds have been taken away.
Russian doping doesn't seem to be an IAAF-crisis that is not being properly managed.
I'm glad you share your expectation that the IAAF should remove doping, but the accusation was that they did not act on the "suspicious profiles". We are not lowering our expectations, but comparing the IAAF to other sports federations/organizations, who are subject to the same WADA guidelines. Nothing in the ARD documentary shows that the IAAF did not act. And in fact history shows, that they did target and catch many Russian women, and many Russian race walkers.
Regarding Kenyan blood testing, this only becomes relevant after the introduction of the blood passport in 2009. In other threads, I have seen accusations that Kenya has been getting away with "no testing" for decades, when the reality is that urine testing always existed, blood collection for any athlete from all countries from the IAAF didn't start until 2001, and the ABP was introduced in 2009. This is what I mean by "over-interpret". Kenyans always have been, and are being tested and they are being caught. It's not perfect, but Kenyans are still blood tested outside of Kenya. Something changed in the last few years to increase the number of Kenyan positives, and the lack of blood data collection from within Kenya to form ABP profiles doesn't seem to have been a complete hindrance.
Your expectation that the IAAF is supposed to "clean the mess" sounds idealistic. In any case, the IAAF are supposed to act within the WADA guidelines, and with other national sports and anti-doping organizations, to catch the dopers, and also work with WADA, to improve detection. We have seen evidence that they are catching dopers, and they are one of the leaders, working with WADA, to improve testing. And we haven't seen any evidence that demonstrates that they ignored, covered up, or otherwise failed to act on the "suspicious" profiles collected.
