I have cert trinity and cert takumi as well as chakrams and Some other decals and stuff . <| sep |> Can anyone catch me up ? A lot ? <| sep |> What ' s the link ? I read many aquariumthemed blogs and are always looking for new ones . <| sep |> I love Paper Kites and CHVRCHES so I think your music taste is spot on . <| sep |> Hmm . Maybe I started running too late then . <| sep |> I suspect the patient zero for this trope is George Stevens ' 1959 adaptation of The Diary of Anne Frank which ends with the siren of an approaching Gestapo truck and heavy knocks on the door , before cutting to a forlorn Otto Frank in the present . I ' ve tried and failed to find a relevant clip online , sorryMy suspicions and feel free to treat them as such that this is the trope originator , is that there are no references to specific Gestapo sirens in any of the narratives I ' ve read , and the whole idea of the Gestapo even having a siren seems a tad counterintuitive to a shadowy state security agency . To stick with Anne Frank or more specifically , Anne Frank The Book , the Life , the Afterlife by Francine ProseThe car arrived without sirens , without haste no one in the office below was alarmed by the appearance of the car until a fat man appeared , and , speaking in Dutch , ordered everyone to be quiet . One of the men who got out of the car wore the uniform of a sergeant in the Jewish Affairs Section of the Gestapo in Holland . Anne Frank ' 59 is very well studied by film historians as it played a central role in the globalisation of Holocaust understanding . Along with the release of the Diary as a book and play earlier in the 1950 s and the opening of the Anne Frank House in Amsterdam in 1960 , it established a particular visual language for the Holocaust that permeated popular culture , including that specific siren sound . Without understanding musical terminology in the slightest , your low notehigh note blast is likely to be simply the common siren scheme found in Europe nee naw nee naw to children everywhere which is suitably discordant and alien enough for American filmmakers in the 1950 s to adopt as shorthand for The authorities are coming but they ' re not like your authorities , they ' re Europeans ! Of course it ' s possible that some very specific memories have added to this where local police agencies collaborated with the Gestapo and survivorsemigrants came to associate this particular sound with the Nazis understandable if your only encounters with the police came as a result of occupation but my conclusion is that it ' s a piece of folklore . But hey , associations are subjective so is perception any less valid than fact ? Oh , it ' s rAskHistorians , so yes .
