The Defense Department’s office of the inspector general issues a report saying allegations made by members of the Able Danger program are unfounded. According to the inspector general, Able Danger did not identify any of the 9/11 hijackers before the attacks, the program’s members were not prevented from sharing this information with the FBI, and there was no retaliation against one person involved in the program, Lieutenant Colonel Anthony Schaffer, after he highlighted the issue in the media. The basis for the main claim that the hijackers were not identified before 9/11 is that the recollections of the people who claim lead hijacker Mohamed Atta was identified “varied significantly.” In addition, the names of Atta and the other 9/11 hijackers said to have been identified by the program were not present in any surviving documentation, although the vast majority of the data gathered by the Able Danger program was destroyed several years ago (see May-June 2000). Concerning the blocking of passage of information to the FBI, the inspector general identified only one occasion when this may have happened, but found that such blocking “would not have been inappropriate under the circumstances.” [Department of Defense Office of the Inspector General, 9/18/2006 ]
