Supreme Court to Define Geofence Warrant Limits

The Supreme Court is hearing a challenge to the use of 'geofence' warrants, which ask companies for location data from every cellphone in a defined area and time window. The case (from a 2019 bank robbery that used a geofence sweep to identify and convict Okello T. Chatrie) asks whether such broad warrants violate the Fourth Amendment's ban on unreasonable searches. — A decision will set a legal precedent that determines how easily police can obtain mass location records and will affect privacy norms, policing tactics, and data‑broker practices nationwide.
