Eichmann was in every respect a painstaking bureaucrat. He at once recorded in the files every discussion he ever had with any of his superiors. He always told me that the most important thing was to be covered at all times by one's superiors. He shunned all personal responsibility and took care to shelter behind his superiors - in this case Mueller and Kaltenbrunner - and inveigle them into accepting liability for his actions.
