The Bank Robbery and the Geofence Warrant
On May 20, 2019, a robber took $195,000 from Call Federal Credit Union in Midlothian, Va. Detectives, noting the suspect’s cellphone, obtained a geofence warrant that forced Google to provide location data for devices within ~150 m of the bank. The data identified Okello T. Chatrie, whose conviction faces a Fourth-Amendment challenge.
Legal Background
The Fourth Amendment bars unreasonable searches. The Court requires warrants for cell-tower data (Carpenter v. U.S., 2018) and forbids warrantless GPS tracking (2012). Geofence warrants reverse the usual model by sweeping data from all nearby devices.
Key Figures & Groups
Okello T. Chatrie; Solicitor General D. John Sauer; Google; Judge Hannah Lauck; 4th Circuit judges Albert Diaz et al.; ACLU; Greg Nojeim (Center for Democracy and Technology); Jake Karr (Knight First Amendment Institute); William McGeveran (law-school dean).
Timeline
- 20 May 2019 – $195,000 robbery.
- Late 2019 – Warrant yields 19 phones; Chatrie identified.
- 2022 – District court ruled search unconstitutional, applying an exception. 4th Circuit split 7-7, deeming data a non-search. No precedent exists; courts remain divided on privacy analysis.
- 27 Apr 2026 – Supreme Court hears case.
Data & Statistics
Google can pinpoint a device within three meters, covering 17.5 acres. Nineteen phones were flagged. Google stored data on >500 million users; geofence requests rose from ~1,000 in 2016 to >11,000 in 2020, a quarter of law-enforcement data demands.
Why It Matters
Geofence warrants would legitimize searches, letting police scan protests or visits without suspicion. A rejection would curb a tool credited with solving cases but limit investigations.
Official Statements & Responses
Solicitor General Sauer says anyone who enables Google’s location data “has no reasonable expectation of privacy,” making it lawful; Nojeim: “turn the Fourth Amendment upside down.” Jake Karr warned “the stuff authoritarian nightmares are made of.”
Criticism & Opposition
ACLU calls them “general warrants” violating Fourth Amendment. Nojeim: “turn the Fourth Amendment upside down.” Jake Karr warned “the stuff authoritarian nightmares are made of.”
Conflicting Reports & Gaps
District court ruled search unconstitutional, applying an exception. 4th Circuit split 7-7, deeming data a non-search. No precedent exists; courts remain divided on privacy analysis.
