The Justice Department announced a policy Thursday that will require its law enforcement agencies to obtain a warrant to deploy cellphone-tracking devices in criminal investigations and inform judges when they plan to use them, reports the Washington Post .
The new policy, announced by Deputy Attorney General Sally Quillian Yates, should increase transparency around the use of the controversial technology by the FBI and other Justice Department agencies. It imposes the highest legal standard for the device's use and a uniform standard across the department.
