Revision History

The U.S. Supreme Court heard oral arguments on April 27, 2026, in Chatrie v. United States, a landmark case that will determine whether police can use "geofence warrants" to compel tech companies like Google to hand over location data on every cellphone user near a crime scene. The case pits law enforcement's need for modern investigative tools against Fourth Amendment protections, with implications for millions of Americans whose phones constantly broadcast their whereabouts to corporate databases.
