When the towers fell on September 11, 2001, nowhere were the reverberations more powerfully felt than at CIA headquarters in Langley, Virginia. Almost overnight, the intelligence organization evolved into a warfighting intelligence service, constructing what was known internally as 'the Program': a web of top-secret detention facilities intended to help prevent future attacks on American soil and around the world. With Black Site, former deputy director of the CIA Counterterrorist Center Philip Mudd presents a full, never-before-told story of this now-controversial program, directly addressing how far America went to pursue al-Qa'ida and prevent another catastrophe. Heated debates about torture were later ignited in 2014 after the U.S. Senate published a report of the Program, detailing the CIA's use of 'enhanced interrogation techniques' to draw information from detainees. The report, Mudd posits, did not fully address key questions: How did the officials actually come to their decisions? What happened at the detention facilities-known as 'Black Sites'-on a day-to-day basis? What did they look like? How were prisoners transported there? And how did the officers feel about what they were doing? Black Site seeks answers to these questions and more.
