Stephen Kinzer, 'Poisoner In Chief,' Chapter 3, Willing and Unwilling Subjects. Pages 43-44.Teams of Bluebird interrogators flew regularly to West Germany to conduct their experiments. Most often, they did their work at Camp King and the nearby "black site" at Villa Schuster. German researchers would later identify other secret prisons where Americans also carried out extreme experiments. One was in Mannheim, near the baroque palace from which princes ruled the Palatinate. Reports have placed others in Berlin, Munich, and the outskirts of Stuttgart.
At these secret prisons, Bluebird interrogators worked without any outside supervision. This set a precedent that marked a breakthrough for the CIA. By opening prisons, the Agency established its right to detain and imprison people in other countries, but to interrogate them harshly while they were in custody without regard for the U.S. law.
