4,000 Pages Of Stingray Surveillance Documents: EPIC

EPIC has obtained nearly $30,000 in litigation fees as a result of a Freedom of Information Act case against the FBI concerning a new surveillance technology. EPIC's lawsuit produced the release of more than 4,000 pages of documents about a phony cell tower technique called "Stingray."

The documents obtained by EPIC revealed that the FBI used the devices to monitor cell phones without a warrant, and provided Stingrays to other law enforcement agencies.
