The FBI had to rewrite the book on its domestic surveillance activities in the wake of last January's landmark Supreme Court decision in United States v. Jones. In Jones, a unanimous court held that federal agents must get a warrant to attach a GPS device to a car to track a suspect for long periods of time. But if you want to see the two memos describing how the FBI has reacted to Jones — and the new surveillance techniques the FBI is using beyond GPS trackers — you're out of luck. The FBI says that information is "private and confidential."
Yes, now that the Supreme Court ruled the government must get a warrant to use its previous go-to surveillance technique, it has now apparently decided that it's easier to just keep everything secret. The ACLU requested the memos under the Freedom of Information Act — which you can see FBI General Counsel Andrew Weissmann waving around in public here — and the FBI redacted them almost entirely.
