British historian A.J.P. Taylor published The Origins of the Second World War in 1961, in which he writes of the Nuremberg Trials:
The evidence of which there is too much is that collected for the trials of war-criminals in Nuremberg. Though these documents look imposing in their endless volumes, they are dangerous material for a historian to use. They were collected, hastily and almost at random, as a basis for lawyers's briefs. This is not how a historian would proceed. The lawyer aims to make a case; the historian wishes to understand a situation. The evidence which convinces lawyers often fails to satisfy us; our methods seem singularly imprecise to them. But even lawyers must now have qualms about the evidence at Nuremberg. The documents were chosen not to demonstrate the war-guilt of the men on trial, but to conceal that of the prosecuting Powers. [....] The verdict preceded the tribunal; and the documents were brought in to sustain a conclusion which had already been settled. Of course the documents are genuine. But they are "loaded"; and anyone who relies on them finds it almost impossible to escape from the load with which they are charged.

Josef Kramer, initially denied the Nazis gassed anyone at Auschwitz
"I have heard of the allegations of former prisoners in Auschwitz referring to a gas chamber there, the mass executions and whippings, the cruelty of the guards employed, and that all that took place either in my presence or with my knowledge. All I can say to all this is that it is untrue from beginning to end."
"The first time I saw a gas chamber proper was at Auschwitz. It was attached to the crematorium. The complete building containing the crematorium and gas chamber was situated in Camp No.2 [Birkenau], of which I was in charge."
Kramer admitted at his trial, that he had personally gassed people at Natzweiler (ignoring his earlier testimony, with "cyanide salts" from a bottle (shake and bake??). And that he drove to the gas chamber in a "small car" with "fifteen women."
