The Circuit Court for the District of Columbia has ruled that the Department of Justice must release information regarding government surveillance of cell phone location data. The American Civil Liberties Union had filed a Freedom of Information Act request for information regarding current and past cases where the Department of Justice had accessed cell phone location data without a warrant. The agency sought to keep this information secret, claiming that releasing cell phone tracking data could implicate privacy of investigation subjects. The court, however, disagreed, stating, "The disclosure sought by the plaintiffs would inform this ongoing public policy discussion by shedding light on the scope and effectiveness of cell phone tracking as a law enforcement tool."
