Documented Incident
Federal judge in Oklahoma suppresses evidence from warrantless Flock plate search
Event: October 1, 2026 · First reported: October 4, 2026 · 63 sources
On October 1, 2026, Judge Sara Hill of the U.S. District Court for the Northern District of Oklahoma ruled that a Tulsa County deputy's warrantless query of Flock and other ALPR databases amounted to a search under the Fourth Amendment. The query, run after the deputy followed a California-plated Mazda SUV on Interstate 44 in May, returned more than 50 hits over roughly a month, tracing the vehicle from the California-Arizona border to Missouri; the deputy then stopped and searched the car, and driver Melisa Kyle, 46, was charged with methamphetamine possession with intent to distribute. Hill suppressed both the Flock data and the evidence from the vehicle search, describing the national camera network as indiscriminate mass surveillance. Flock Safety told 404 Media the order conflicts with existing case law and said it expects it to be reversed on appeal.
The decision is one of the first federal rulings to treat historical ALPR lookups as a Fourth Amendment search rather than observation of publicly visible plates, though as a district court order it binds no other court. Similar challenges are pending elsewhere, and the reasoning could shape how agencies document and justify database queries.
Key facts
- Ruling issued October 1, 2026 by Judge Sara Hill, Northern District of Oklahoma; it is a district court decision and sets no binding precedent.
- The deputy searched ALPR systems before citing any traffic infraction; the stop was later made for an alleged lane change without signaling.
- Hill said United States v. Knotts (1983) has been misapplied to networked plate readers, and cited the Fifth Circuit's March 2026 decision in United States v. Porter.
- Flock Safety says the order contradicts prevailing case law and anticipates reversal on appeal; charges against Kyle remain pending, with key evidence excluded.
- On October 2, Sens. Bernie Sanders and Jeff Merkley and Rep. Alexandria Ocasio-Cortez introduced the Ban Flock Act, a proposal that has not been enacted, to bar federal agencies from using ALPRs or their data.
