ehhhhhhhh I'm not so sure on that. A lot of the macabre practices that were performed inside the concentration camps were kept under tight wraps.
Like Mengele's experiments. Hardly anyone was privy to what exactly he was doing, aside from those that saw it first hand / the doctors he was in communication with. The records were destroyed, and the witnesses....well...you know.
Sounds like the camarillo state mental hospital.
