Supreme Court Weighs Privacy Against Geofence Warrants in Robbery Case

Police need every tool to solve violent crimes, yet the digital dragnet required to catch one Virginia bank robber now threatens to redraw constitutional lines on government surveillance. On Monday, the Supreme Court heard arguments in Chatrie v. United States over whether investigators needed a warrant to obtain Google location data that identified Okello Chatrie as the armed robber who stole $195,000 from a Midlothian credit union on May 20, 2019. The case pits Fourth Amendment protections against a law enforcement technique that has become routine as smartphones constantly track movement.

The central tension is whether a "geofence warrant" ordering Google to search its Location History database for every device within a defined area and time frame counts as a search requiring probable cause, or whether users who opt into sharing their data have surrendered any expectation of privacy. In this instance, according to court records and briefs filed with the Supreme Court, a federal magistrate approved the warrant after detectives saw a man on bank surveillance video holding a cellphone. The geofence covered a 150-meter radius for roughly one hour around the robbery; Google initially identified 19 accounts with Location History enabled. Iterative narrowing by investigators led them to Chatrie, whose data placed him at the scene shortly before the crime and showed him leaving immediately afterward. He was convicted of armed robbery and brandishing a firearm.

Lower courts, including the Eastern District of Virginia and the Fourth Circuit, upheld the warrant as supported by probable cause given the narrow parameters and corroborating evidence. Chatrie's lawyers counter that the technique is inherently a "search first and develop suspicions later" approach the Fourth Amendment was written to prevent. It can sweep in data from hundreds or thousands of bystanders. The Justice Department maintains that people voluntarily share this information with Google, that the movements involved were public, and that the three-step warrant process with a magistrate provided sufficient safeguards. The government brief warned that ruling against such warrants would effectively ban them entirely and outpace ongoing legislative and common-law development of digital privacy rules.

This is not the court's first encounter with location tracking. In its 2018 Carpenter v. United States decision, justices required warrants for cell-tower data revealing long-term movements. Geofence warrants differ by seeking information from all devices in a geographic "fence" rather than targeting one person. Privacy groups argue the tool risks abuse against protesters, worshippers or political gatherings. Law enforcement cites its value in cases where traditional leads are absent. Google told the court it no longer responds to geofence requests for Location History because the data now resides primarily on users' devices rather than company servers, though the company urged Fourth Amendment protection for remotely stored digital records.

Oral arguments on April 27, 2026, mark the final week of the term for such hearings, with a decision expected by late June. The outcome will shape how police investigate crimes in an era when phones generate constant location records, determining whether judges must continue approving these warrants or if broader access becomes constitutionally permissible. Both the specific facts of Chatrie's robbery and the wider implications for millions of daily location pings hung over the proceedings.
