"An ambiguous presidential finding, issued during the post-9/11 turmoil, gave sweeping powers to the CIA. U.S. president George W. Bush signed a secret document - known as a presidential finding, which is the only means under U.S. law by which covert activities may be legally sanctioned, that gave the Central Intelligence Agency (CIA) sweeping authority to expand its counter-terrorism operations, including the prerogative to detain, even to kill, any al-Qaeda member worldwide.
