D.C. Judge: Warrants not needed for cell phone location data

These days, most people carry a cell phone with them everywhere they go: to work, to church, on vacation, and more. And cell phone carriers may capture and retain records of your location even when you’re not using your phone. Does that mean that the government can simply demand these records from your carrier without a warrant? Unfortunately, according to Judge Royce Lamberth of the D.C. District Court, the answer to that question is ‘yes.’ (ACLU)
