McGruber writes "The New York Times is reporting on yet another NSA revelation: for the last three years, the National Security Agency has been exploiting its huge collections of data to create sophisticated graphs of some Americans' social connections that can identify their associates, their locations at certain times, their traveling companions and other personal information. 'The agency can augment the communications data with material from public, commercial and other sources, including bank codes, insurance information, Facebook profiles, passenger manifests, voter registration rolls and GPS location information, as well as property records and unspecified tax data, according to the documents. They do not indicate any restrictions on the use of such "enrichment" data, and several former senior Obama administration officials said the agency drew on it for both Americans and foreigners.' In a memorandum, NSA analysts were 'told that they could trace the contacts of Americans as long as they cited a foreign intelligence justification.' 'That could include anything from ties to terrorism, weapons proliferation or international drug smuggling to spying on conversations of foreign politicians, business figures or activists. Analysts were warned to follow existing "minimization rules," which prohibit the NSA from sharing with other agencies names and other details of Americans whose communications are collected, unless they are necessary to understand foreign intelligence reports or there is evidence of a crime. The agency is required to obtain a warrant from the intelligence court to target a "U.S. person" — a citizen or legal resident — for actual eavesdropping.'"
