Isn’t the German term for Special Police, “S”chutz”S”taffen?
SS stood for Schutzstaffel, which usually translates as "protective squad," which makes sense because they started at Hitler's bodyguards. "Gestapo" was a contraction of "Geheime Staatspolize"--Secret State Police. Then there were the Sonderkommando, which translates as "Special Squads"--they were the Jews in the camps forced to aid in the extermination (for a few weeks or months, before being killed themselves because they knew too much). Finally, there were the Einsatzgruppen, which translates to "task force" or "intervention group:. They were the ones travelling the countryside in eastern Europe and the Soviet Union killing "undesirables" without the formality of shipping them to death camps.
In today's society it is more properly named "Sh!t Stuffin"
