The book also contains Shaffer's allegations that the DIA's Able Danger program identified hijacker Mohamed Atta before the September 11 attacks. However on December 22, 2006, a 16-month investigation by the Senate Intelligence Committee concluded that Able Danger, "did not identify Mohamed Atta or any other 9/11 hijacker at any time prior to September 11, 2001,". The Defense Department's inspector general (DoD OIG) made a similar conclusion.
