|A recent Supreme Court ruling is forcing the FBI to deactivate its GPS tracking devices in some investigations, agency director Robert Mueller said Wednesday.
Mueller told a congressional panel that the bureau has turned off a substantial number of GPS units and is using surveillance by agents instead.
'Putting a physical surveillance team out with six, eight, 12 persons is tremendously time intensive,' Mueller told a House Appropriations subcommittee. The court ruling 'will inhibit our ability to use this in a number of surveillances where it has been tremendously beneficial.'
Mueller declined to say how many devices were deactivated. The FBI's general counsel said at a law school conference two weeks ago that the FBI has 3,000 GPS devices.
