Is this in your opinion the strongest positive evidence you've seen in support of the revisionist hypothesis (no mass killing / they were instead sent east)?"The Auschwitz regulations strictly prohibited the SS from killing or arbitrarily mistreating an inmate. SS personnel who were transferred to the
camp had to sign the following “Pledge”:32 “I am aware that only the Führer may decide upon the life and death of an enemy of the state. I may not physically harm or kill any opponent of the state (inmate). Any killing of an inmate in a concentration camp requires the personal authorization of Reichsführer SS [Himmler]. I am also aware that any violation of this pledge will be inexorably accounted for. CC Auschwitz, [day missing] November 1943."
