I don't know if this belongs in this section, but it is post 1945.
I was reading a bit about the Gehlen organization today and found a list of some of the people who had been in the organization. I can understand ex-gestapo, maybe ex einstatzgruppen members, at a push. However a lot of the listed names had worked at death camps. I don't understand the Western Allies, well specifically the Americans, as they controlled the Gehlen organization at the beginning, allowing these people to get away with what they had done because, to me, being at a death camp has no relation to being a spy. There was an inference that if the full list was available there would be more of these type of people on it. Was it just a case of Gehlen saying " Yes he worked at Autschwitz, but he is really an expert at intelligence" and the Americans being so desperate to have some sort of spying on the Soviets that they just went with it. A bit simplistic, but I hope you see what I mean.
