The documents reveal what had been a mostly secretive process that allows the government to create a travel alert for a person (regardless of whether they're a suspect in an investigation), then detain that individual at a border crossing and confiscate or copy any electronic devices that person is carrying. The documents come courtesy of David House, a fund-raiser for the legal defense of Chelsea Manning, formerly known as Pfc. Bradley Manning."
