FBI No Longer Using GPS

The FBI has turned off GPS devices it was using to track suspected terrorists. Director Robert Mueller told members of Congress a Supreme Court ruling has forced the FBI to use human surveillance instead, which Mueller said was time-consuming and expensive. In a case involving a nightclub owner, the court unanimously agreed that planting a GPS device on someone violated privacy laws and required a judge's prior approval. The FBI operates thousands of tracking devices. Mueller didn't disclose how many it has deactivated.
