Able Danger was a classified military planning effort led by the U.S. Special Operations Command (SOCOM) and the Defense Intelligence Agency (DIA). It was created as a result of a directive from the Joint Chiefs of Staff in early October 1999 by Chairman of the Joint Chiefs of Staff Hugh Shelton, to develop an information operations campaign plan against transnational terrorism. According to statements by Lt. Col. Anthony Shaffer and those of four others, Able Danger had identified 2 of 3 Al Qaeda cells active in the 9/11 attacks; the 'Brooklyn cell' linked to "Blind Sheik" Omar Abdel-Rahman, including September 11 attacks leader Mohamed Atta, and three of the 9/11 plot's other 19 hijackers. In December 2006, a sixteen-month investigation by the US Senate Intelligence Committee concluded "Able Danger did not identify Mohamed Atta or any other 9/11 hijacker at any time prior to September 11, 2001," and dismissed other assertions that have fueled 9/11 conspiracy theories. The Senate Judiciary Committee first attempted to investigate the matter for the Senate in September, 2005. The Pentagon "ordered five key witnesses not to testify", according to Senate Judiciary Committee Chairman Arlen Specter. "That looks to me as if it may be obstruction of the committee's activities," Specter, R-Pennsylvania, said at the start of his committee's hearing into the unit. Attorney Mark Zaid, representing Lt. Colonel Anthony Shaffer and the other four Able Danger employees at the Senate Judiciary Committee hearing in September 2005, pointed out to the Committee that his clients had been forbidden by the Pentagon to testify to the Committee. He also discussed the Defense Intelligence Agency's decision to suspend Lt. Colonel Shaffer's security clearance shortly after it became known that he had provided information to the 9/11 Commission on Able Danger. "Based on years of experience I can say categorically that the basis for the revocation was questionable at best." An investigation by the Defense Department Inspector General's office (IG) in September 2006 concluded that "the evidence did not support assertions that Able Danger identified the September 11, 2001, terrorists nearly a year before the attack, that Able Danger team members were prohibited from sharing information with law enforcement authorities, or that DoD officials acted against LTC Shaffer for his disclosures regarding Able Danger." However, some of the people questioned by the IG claimed their statements to the IG were distorted by investigators in the final IG's report, and the report omitted essential information that they had provided. Lt. Col Tony Shaffer has claimed that the DOD retaliated against him for speaking out publicly about the IG report's distortions.〔 The Senate panel of investigators said there was no evidence DoD lawyers stopped analysts from sharing findings with the FBI before the attacks. Analysts had created charts that included pictures of then-known Al Qaeda operatives, but none including Atta. A follow-up chart made after the attacks did show Atta. The Senate Committee said its findings were consistent with those of the DoD inspector general, released in September 2006. ==Overview== The program used data mining techniques to associate open source information with classified information in an attempt to make connections among individual members of terrorist groups as part of its original "intelligence preparation of the battlespace". The objective of this particular project was to ascertain whether the data mining techniques and open source material were effective tools in determining terrorist activities, and if the resultant data could be used to create operational plans that could be executed in a timely fashion to interrupt, capture and/or destroy terrorists or their cells.〔An example of a chart produced as output by the project's data mining and visualization suite is called the (3.21.00 Chart ). (DIAC Link Chart declassified 3.21.00, produced on March 21, 2000, and reproduced on author Peter Lance's website for his book Triple Cross Another barely readable sample chart was published by the Defense Department's Inspector General's Office on page 14 of the (Able Danger Investigation Report ).〕〔Patience Wait has reported that a follow-on project appears to have been funded and implemented by the Intelligence Community and was originally named Able Providence. (Data Mining Offensive in the Works ) - Patience Wait - GCN Magazine, 10/10/2005〕 According to statements by Lt. Col. Anthony Shaffer and those of four others, Able Danger had identified 2 of 3 Al Qaeda cells active in the 9/11 attacks; the 'Brooklyn cell' linked to Blind Sheik Omar Abdel-Rahman, including September 11 attacks leader Mohamed Atta, and three of the 9/11 plot's other 19 hijackers, as possible members of an al Qaeda cell linked to the 1993 World Trade Center bombing. This theory was heavily investigated and researched by Republican Representative Curt Weldon, vice chairman of the House Armed Services and House Homeland Security committees. However, Defense Intelligence Agency leadership had already ordered the hurried destruction of mined data, source databases, charts & resultant documents on entirely spurious legal grounds. DIA also prevented key personnel from testifying to both the Senate Judiciary & Senate Intelligence Committees, though after numerous denials did admit the program's existence. In December 2006, an investigation by the US Senate Intelligence Committee concluded that assertions could not be confirmed. It stated that they were unable to find supporting evidence regarding "one of the most disturbing claims about the Sept. 11 terrorist strikes."〔 This report released by the Senate Intelligence Committee copied, nearly verbatim, the United States Department of Defense Inspector General's September 2006 report on Able Danger. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Able Danger」の詳細全文を読む スポンサード リンク
