August 17, 2005: Intelligence Officer Comes Forward with Allegations about Secret Military Unit Called Able Danger

A US Army intelligence officer comes forward, saying he was involved with a secret military intelligence unit, which had identified Mohamed Atta and three other future 9/11 hijackers by mid-2000. He says the unit, called Able Danger, had tried to meet with agents at the FBI’s Washington field office that summer to share its information, but was prevented from doing so by military lawyers (see September 2000). Lt. Col. Anthony Shaffer, who served as a liaison officer between Able Danger and the Defense Intelligence Agency, is the first military officer associated with Able Danger to publicly acknowledge his involvement with the unit. Shaffer says that, had they been allowed to alert the FBI to Mohamed Atta being in the US, they might have been able to prevent 9/11. [New York Times, 8/17/2005; Guardian, 8/18/2005; New York Post, 8/18/2005] A week prior to Shaffer’s coming forward, Able Danger was brought to the public’s attention in a New York Times front page article (see August 9, 2005). Shaffer says he met privately with staff from the 9/11 Commission in Afghanistan in October 2003, and explicitly mentioned Atta as a member of the “Brooklyn” al-Qaeda cell (see October 21, 2003).
