The NSA's media defenders have similarly stressed that the NSA's eavesdropping and internet snooping requires warrants when it involves Americans. The Washington Post's Charles Lane told his readers: "the government needs a court-issued warrant, based on probable cause, to listen in on phone calls." The Post's David Ignatius told Post readers that NSA internet surveillance "is overseen by judges who sit on the Foreign Intelligence Surveillance Court" and is "lawful and controlled". Tom Friedman told New York Times readers that before NSA analysts can invade the content of calls and emails, they "have to go to a judge to get a warrant to actually look at the content under guidelines set by Congress."
This has become the most common theme for those defending NSA surveillance. But these claim are highly misleading, and in some cases outright false.
Top secret documents obtained by the Guardian illustrate what the Fisa court actually does – and does not do – when purporting to engage in "oversight" over the NSA's domestic spying. That process lacks many of the safeguards that Obama, the House GOP, and various media defenders of the NSA are trying to lead the public to believe exist.
