The video in question, a documentary, was produced by the National Geographic Channel and documents the events of September 11, 2001, as well as the chain of events leading up to that fateful day. The terrorist attacks on the World Trade Center and the Pentagon, and the aborted attack on a third, never definitively identified target (almost certainly the U.S. Capitol Building, but possibly also the White House) represented the most devastating attack on American soil in this country’s history—more destructive and costly in terms of human losses than the December 1941 surprise attack on Pearl Harbor. The documentary was an attempt to illuminate for the public the reasons the attack was so successful despite the vast resources annually spent purportedly to keep the country safe.
The failures among US agencies that enabled 19 young men from the Middle East (15 from Saudi Arabia) to hijack four aircraft and fly three of them into prominent buildings in New York and Virginia are discussed in detail, with emphasis on the inability and/or unwillingness on the part of the Central Intelligence Agency to provide its domestic law enforcement counterpart, the Federal Bureau of Investigation, with important information that might have prevented the attacks. That failure to communicate essential information had its roots in these agencies' abuses of their powers during the anti-Vietnam War protests of the 1960s and 1970s. Congressional investigations (the Church and Pike Committee hearings) had resulted in the establishment of rigid boundaries separating the foreign intelligence mission and activities of the CIA from the domestic law enforcement responsibilities of the FBI. Those statutory boundaries—as well as the cultural barriers between those two federal government agencies—played a major role in the failure to obstruct the terrorist attacks. Specifically, the CIA, which had tracked two of the terrorists in Yemen, Dubai and Malaysia, had not relayed its information on those individuals to the FBI following the terrorists’ entry into the United States. The CIA is prohibited by law from spying within the United States and was similarly precluded from sharing information with the FBI. Had the FBI been provided the information on the two terrorist suspects, it might have been able to arrest them or, at a minimum, impede their ability to carry out the attack.
Another failure discussed in the documentary involved the lack of foresight and innovation on the part of US counter-terrorism officials. As Special Counsel to the 9/11 Commission and retired law enforcement official John Farmer is quoted as saying, “procedures in place didn’t contemplate hijackers who would proceed to destroy the plane.” Farmer’s point was about the observation provided earlier in the video by the head of the Federal Aviation Administration—that hijackings generally ended without incident, so the scrambling of interceptor jets to shoot down the hijacked aircraft was not contemplated. In short, a myopic view of terrorism and aviation safety precluded officials from considering the possibility of suicide operations involving aircraft.
These are the main points made in the video. Farmer's statement that the laws separating the CIA from the FBI became “an excuse not to share information,” along with the inability of counter-terrorism officials to anticipate variations in patterns relating to aviation security and hijackings, represented major failings that enabled the terrorists to accomplish their objective.
