The Supreme Court heard arguments in Chatrie v. United States, a landmark Fourth Amendment case challenging police use of "geofence warrants" to demand location data from tech companies. Police used Google Location History data to track down a 2019 bank robbery suspect by requesting information on everyone within 300 meters of the crime scene. The court's ruling will determine whether such warrants violate constitutional privacy protections or fall under the "third party doctrine."
