I can say with a high degree of certainty that there was no specific Gestapo siren . There is no mention of such in the pertinent literature on the Gestapo or Carolyn Birdsall ' book Nazi Soundscapes Sound , Technology and Urban Space in Germany , 19331945 . Additionally , it is not accurate to imagine the Gestapo as an organization similar to regular police . The Gestapo , which is short for Geheime Staatspolizei , was the Nazi successor to the what in the Weimar Republic had been the political police , such as the Preuische Geheimpolizei . A political police is , as it sounds , a police force charged with the prevention of crimes of a political nature something , which albeit it had a tradition e . g . in the German Empire had seem very essential during Weimar times because of the excessive and often violent nature of political conflict , for example between communist and rightwing groups . The Gestapo was specifically charged with the persecution of political enemies , which in the Third Reich included Jews . In 1936 the regular police and the SS were merged and the regular police e . g . the criminal police , the Schutzpolizei , which was the people patrroling the streets in uniform , the Gendarmerie , the rural uniformed police , and other branches of police forces came under the control of Heinrich Himmler and the SS . While this transferred massive executive powers into the hands of the Gestapo and laid the ground work for them becoming a sort of judgejuryexecutioner all in one insitution later on during the war , the Gestapo could take over cases and hand out punishment imediately without a trial . Still , the Gestapo is best not imagined as something resembling a regular police force with police cars with sirens . You couldn ' t get on your phone and call the German equivalent of 911 which is 110 btw . and get the Gestapo to come to some place with sirens blaring . Rather , they either came because people were suspected of being political enemies or to supervise the arrest and deportation of Jews e . g . Also , if they came to arrest a person , they did not do so using sirens and blue lights but rather turned up at your doorstep at 4 am in the morning . It ' s best to imagine them akin to the homocide division in American police forces , i . e . they get called in when needed or set out to investigate and arrest people . When they needed such a thing like a siren like in the case of the Greiferkommandos , squds of police under Gestapo supervision roving the streets of Berlin in 194243 and arresting people wearing the Jewsih star at randomo , they used cars from the regular German police and their sirens might have sounded similar to what you have in mind . All in all though , sirens are not as far as my knowledge goes particularly associated with the Gestapo and I too like uJDHoare suspect that this might be something that started as a pop culture trope rather than having a historical basis per se .
