The Obama administration has quietly approved a substantial expansion of the terrorist watchlist system, authorizing a secret process that requires neither concrete facts" nor "irrefutable evidence" to designate an American or foreigner as a terrorist. The "March 2013 Watchlisting Guidance," a 166-page document issued last year by the National Counterterrorism Center, spells out the government's secret rules for putting individuals on its main terrorist database, as well as the no fly list and the selectee list, which triggers enhanced screening at airports and border crossings. The new guidelines allow individuals to be designated as representatives of terror organizations without any evidence they are actually connected to such organizations, and it gives a single White House official the unilateral authority to place entire "categories" of people the government is tracking onto the no fly and selectee lists. It broadens the authority of government officials to "nominate" people to the watchlists based on what is vaguely described as "fragmentary information." It also allows for dead people to be watchlisted. The rulebook ... was developed behind closed doors by representatives of the nation's intelligence, military, and law-enforcement establishment, including the Pentagon, CIA, NSA, and FBI. Emblazoned with the crests of 19 agencies, it offers the most complete and revealing look into the secret history of the government's terror list policies to date.
