NSA Buys Americans' Internet Data Without Warrants, Letter Says

The National Security Agency buys certain logs related to Americans' domestic internet activities from commercial data brokers, according to an unclassified letter by the agency. The New York Times: The letter [PDF], addressed to a Democratic senator and obtained by The New York Times, offered few details about the nature of the data other than to stress that it did not include the content of internet communications. Still, the revelation is the latest disclosure to bring to the fore a legal gray zone: Intelligence and law enforcement agencies sometimes purchase potentially sensitive and revealing domestic data from brokers that would require a court order to acquire directly. It comes as the Federal Trade Commission has started cracking down on companies that trade in personal location data that was gathered from smartphone apps and sold without people's knowledge and consent about where it would end up and for what purpose it would be used. In a letter to the director of national intelligence dated Thursday, the senator, Ron Wyden, Democrat of Oregon, argued that "internet metadata" -- logs showing when two computers have communicated, but not the content of any message -- "can be equally sensitive" as the location data the F.T.C. is targeting. He urged intelligence agencies to stop buying internet data about Americans if it was not collected under the standard the F.T.C. has laid out for location records. "The U.S. government should not be funding and legitimizing a shady industry whose flagrant violations of Americans' privacy are not just unethical, but illegal," Mr. Wyden wrote.
