The CIA sends an officer from its Counterterrorist Center (CTC) to the NSA to review raw transcripts of intercepted communications between terrorists. However, the officer is only there for a “brief period” and is subsequently withdrawn and not replaced, damaging the CIA’s ability to exploit the information gleaned from the intercepts. The CIA only previously received summaries of intercepted calls, not the transcripts themselves, and had been arguing for years that it needed the actual transcripts to better understand the material (see February 1996-May 1998, December 1996, After December 1996, After December 1996, and Late August 1998). After the single officer leaves the NSA, which intercepts calls between the US-based 9/11 hijackers and an al-Qaeda communications hub in Yemen around this time (see Early 2000-Summer 2001), the reason the CIA gives for not replacing him is “resource constraints.” In 2005, the CIA’s Office of Inspector General will regard this failure as so serious that it will recommend an accountability board be convened to review the performance of the CTC managers responsible, and will suggest that officers should have been detailed to the NSA “on a consistent, full-time basis.” [Central Intelligence Agency, 6/2005, pp. xxiii ] The CIA and NSA are obtaining information about people in the US from phone companies to support “black ops” at this time (see After July 11, 1997).
