None of the six individuals targeted by the NSA is accused in the document of being involved in terror plots. The agency believes they all currently reside outside the United States. It identifies one of them, however, as a "U.S. person," which means he is either a U.S. citizen or a permanent resident. A U.S. person is entitled to greater legal protections against NSA surveillance than foreigners are.

Stewart Baker, a one-time general counsel for the NSA and a top Homeland Security official in the Bush administration, said that the idea of using potentially embarrassing information to undermine targets is a sound one. "If people are engaged in trying to recruit folks to kill Americans and we can discredit them, we ought to," said Baker. "On the whole, it's fairer and maybe more humane" than bombing a target, he said, describing the tactic as "dropping the truth on them."
