https://www.theguardian.com/us-news/2016/jun/15/cia-torture-program-september-11-medical-staff-instructions-details This is an extremely disturbing declassified report on how CIA medical staff gave specific details on how to torture post 9/11 detainees. It is very detailed, and not for the faint-hearted. To me it brings a comparison with the fact that the Nazis employed medical staff in their torture experiments in WWII.
