US Supreme Court appears split over controversial use of ‘geofence’ search warrants

The U.S. Supreme Court on Monday heard arguments in a landmark legal case that could redefine digital privacy rights for people across the United States.

The case, Chatrie v. United States, centers on the government’s controversial use of so-called “geofence” search warrants. Law enforcement and federal agents use these warrants to compel tech companies, like Google, to turn over information about which of its billions of users were in a certain place and time based on their phone’s location.
