"Under the Electronic Communications Privacy Act (ECPA) 18 U.S.C. section 2709, the FBI can seek “the name, address, length of service, and local and long distance toll billing records” of a subscriber to a wire or electronic communications service. The FBI can’t use NSLs to obtain anything else from Google, such as Gmail content, search queries, YouTube videos or user IP addresses."
