instruct its employees to participate in interviews. notwithstanding this, i am really confident of the factual accuracy and comprehensive nature of this report for three reasons. first, it's the 6.3 million pages of documents reviewed, ask they reveal records of actions as those actions took place, not through recollections more than a decade later. second, the cia and cia senior officers have taken the opportunity to explain their views on cia detention and interrogation of operations. they have done this in on-the-record statements in classified committee hearings, written testimony and answer to questions and through the formal response to the committee in june 2013 after reading the study.
