to the Measures of Self-Defense of the State") had been passed by the Reich Cabinet on July 3, which declared: "Die zur Niederschlagung hoch- und landesverräterischer Angriffe am 30. Juni, 1. und 2. Juli 1934 vollzogenen Maßnahmen sind als Staatsnotwehr rechtens" ("The measures taken to clamp down on the treasonous attacks of June 30th, July 1st and 2nd are rightful, due to having been acts of self-defense of the State.") it was decided that the killing of everybody on that list was to be considered lawful and that therefore the police and Attorney Offices were prohibited from investigating and prosecuting anyone for those killings. The lists thus were used by the Ministry and the Gestapo as a referential tool which could be consulted to decide, whether requests of relatives and friends of those killed to be given information on the circumstances of death of their beloved ones, or requests to prosecute those responsible for their killing would be answered in the affirmative (people killed and not mentioned on the Gestapo list) or in the negative (people whose names were to be found on the list). The same applied to requests of other state authorities (especially police departments and Attorney Offices) who inquired at the Ministry of Justice or the Gestapo headquarters whether they should open and or continue investigation of a specific killing that had taken place on the three days from June 30 to July 2. The official list of those killed was first published in 1964 by Heinrich Bennecke (1902–1972) in the appendix of his book Die Reichswehr und der "Röhm-Putsch". Estimates of people killed in addition to those on the official list Later research by historians has shown that in addition to those listed by the Gestapo a number of others also had been killed. Heinrich Bennecke complemented the names of the city clerk Kuno Kamphausen from Waldenburg and the music critic Willi Schmid to his reprint of the official Gestapo list, whereupon he concluded that at least 85 people were killed during the purge. Later, Hans Günther Richardi, in his study on the Dachau concentration camp, added the names of four inmates of Dachau (lawyer Julius Adler (1882–1934), worker Erich Gans (1908–1934), Walter Häbich and worker Adam Hereth (1897-1934)), claiming they were murdered by the SS during the purge. In 1993 Otto Gritschneder published a book on the post–World War II prosecution of those involved in
