Following the issue of another directive governing a set of operations against Osama bin Laden, the CIA is said to become confused over whether it can mount an operation to assassinate him. In December, President Bill Clinton authorized the CIA to kill bin Laden using a group of tribal leaders in Afghanistan (see December 24, 1998), but a few weeks later he issued another memo governing relations between the CIA and the Northern Alliance that did not contain authorization to kill bin Laden (see February 1999). The CIA will later say that the reason it does not take advantage of the authorization to kill him using the tribal leaders is because it is confused by the second memo. The CIA’s inspector general will comment: “Given the law, executive order, and past problems with covert action programs, CIA managers refused to take advantage of the ambiguities that did exist.” The 9/11 Commission will also say that “the limits of the available authority were not tested.” [9/11 Commission, 7/24/2004, pp. 133; Central Intelligence Agency, 6/2005, pp. xxi ]
