The U.S. Supreme Court on Monday heard arguments over whether law enforcement can use geofence search warrants to identify criminal suspects by sweeping up location data from tech companies. The case centers on a 2019 armed robbery in Detroit where police obtained a warrant requiring Google to provide anonymized data for devices near the crime scene during the relevant time frame.
Justices questioned whether such warrants violate the Fourth Amendment’s protection against unreasonable searches. The government argues geofence warrants are a modern tool for crime-solving, while civil liberties groups warn they amount to mass surveillance. Police say the method helps locate suspects when traditional methods fail.
During oral arguments, some justices appeared skeptical of the practice. Justice Sonia Sotomayor noted that geofence warrants could scoop up data from innocent people, calling it a ‘digital dragnet.’ Others, like Justice Samuel Alito, suggested the warrants could be limited to specific circumstances to avoid overreach.
The case could set a precedent for how law enforcement accesses digital evidence. Tech companies including Google have pushed back, arguing that geofence warrants force them to hand over vast amounts of user data without individualized suspicion. The court’s decision is expected by summer 2026.
