endangering the state". Wasting no time, Himmler set the SD in motion as they began creating an extensive card-index of the Nazi regime's political opponents, arresting labor organizers, socialists, Jewish leaders, journalists, and communists in the process, sending them to the newly established prison facility near Munich, Dachau. Himmler's SS and SD made their presence felt at once by helping rid the regime of its known political enemies and its perceived ones, as well. As far as Heydrich and Himmler were concerned, the SD left their mission somewhat vaguely defined so as to "remain an instrument for all eventualities". One such eventuality would soon arise. For a while, the SS competed with the Sturmabteilung (SA) for influence within Germany. Himmler distrusted the SA and came to deplore the "rabble-rousing" brownshirts (despite once having been a member) and what he saw as indecent sexual deviants amid its leadership. At least one pretext to secure additional influence for Himmler's SS and Heydrich's SD in "protecting" Hitler and securing his absolute trust in their intelligence collection abilities, involved thwarting a plot from Ernst Roehm's SA using subversive means. On 20 April 1934 Hermann Göring handed over control of the Geheime Staatspolizei (Gestapo) to Himmler. Heydrich, named chief of the Gestapo by Himmler on 22 April 1934, also continued as head of the SD. These events further extended Himmler's control of the security mechanism of the Reich, which by proxy also strengthened the surveillance power of Heydrich's SD, as both entities methodically infiltrated every police agency in Germany. Subsequently, the SD was made the sole "party information service" on 9 June 1934. Under pressure from the Reichswehr (German armed forces) leadership (whose members viewed the enormous armed forces of the SA as an existential threat) and with the collusion of Göring, Joseph Goebbels, the Gestapo and SD, Hitler was led to believe that Röhm's SA posed a serious conspiratorial threat requiring a drastic and immediate solution. For its part, the SD provided fictitious information that there was an assassination plot on Hitler's life and that an SA putsch to assume power was imminent since the SA were allegedly amassing weapons. Additionally, reports were coming into the SD and Gestapo that the vulgarity of the SA's behavior was damaging the party and was even making antisemitism less palatable. On 30 June 1934 the SS and Gestapo acted in coordinated mass arrests that continued for two
