Career with SD
While teaching at Friesing, Hartl became involved with a group of priests who had joined the Nazi Party, and in 1933 he signed up as a paid SD informant. He reported Father Josef Rossberger, apparently his best friend, for anti-Nazi activity, which led to Rossberger's trial and imprisonment, and Hartl becoming a protégé of Reinhard Heydrich, head of the SD. Consequently Hartl renounced the priesthood and joined the SD himself.Шаблон:Sfn[1] In 1935, according to Gitta Sereny, he became the SD's Chief of Church Information, Шаблон:Sfn and was tasked with the collection of information about party members that had close association with the church and collecting information from them.[2] In March 1941, when the Reich Security Head Office was reorganized, he was placed in charge of a Gestapo office known as IV B ("Sects").
