http://ttvpictures.co.uk – "Sonderkommando", broadcast on the History Channel, tells the shocking tale of the Jewish inmates of the death camps whose job it was to pacify and herd new arrivals to the camp into the gas chambers.
(*See: https://en.wikipedia.org/wiki/Sonderkommando. Sonderkommandos were work units made up of German Nazi death camp prisoners. They were composed almost entirely of Jews who were forced, on threat of their own deaths, to aid with the disposal of gas chamber victims during the Holocaust. The death-camp Sonderkommandos, who were always inmates, should not be confused with the SS-Sonderkommandos which were ad hoc units formed from various SS offices between 1938 and 1945.
