Supreme Court Restricts Warrantless Geofence Searches

The Supreme Court ruled that police cannot use geofence warrants—searches that pull location data from all phones in a geographic area—without showing probable cause and getting a judge's approval first. The decision builds on 2018 precedent that protected individuals from mass tracking. Police may still use geofence warrants if they meet constitutional standards. Questions remain about real-time monitoring and searches beyond geofencing.
