EFF points out that three longstanding statutes protect the privacy of Americans' communications from wholesale, unwarranted government surveillance: Title III (The Wiretap Act), the Foreign Intelligence Surveillance Act, and the Stored Communications Act. It also notes that the Constitution forbids such surveillance. Like EFF's earlier case, Hepting v. AT&T, the Jewel case relies in part on the whistleblower evidence uncovered by former AT&T technician, Mark Klein, detailing a secret facility at the Folsom Street office of AT&T in San Francisco where copies of private customer communications are routinely given to the NSA.
