" The FBI has quietly revised its privacy rules for searching data involving Americans’ international communications that was collected by the National Security Agency, US officials have confirmed to the Guardian.
The classified revisions were accepted by the secret US court that governs surveillance, during its annual recertification of the agencies’ broad surveillance powers. The new rules affect a set of powers colloquially known as Section 702, the portion of the law that authorizes the NSA’s sweeping “Prism” program to collect internet data. Section 702 falls under the Foreign Intelligence Surveillance Act (Fisa), and is a provision set to expire in 2017."
