Judge Hill Suppresses Meth Evidence After Warrantless Flock ALPR Query in Tulsa

The October 2026 order in the Northern District of Oklahoma found the deputy had no individualized suspicion beyond the out-of-state plate. Hill held that passive, network-wide collection of location data over time converts public travel into a searchable historical record requiring a warrant. The ruling cites Carpenter v. United States directly and distinguishes targeted tracking from Flock’s always-on ingestion of every passing vehicle.

Flock’s 2024-2025 deployment data show over 40,000 cameras ingesting 3.2 billion plate reads monthly. Jurisdictions in Florida, Texas, and Virginia have already terminated contracts citing identical retention and access policies. Sanders’ Block Flock Act, introduced the same week, would codify warrant requirements for any federal agency use of automated license plate readers.

The decision exposes operational risk for agencies relying on Flock’s on-demand portal. Evidence obtained after an unconstitutional query is now presumptively excludable in at least one district. Departments must either implement pre-search warrant workflows or accept case-by-case suppression motions that scale with query volume.

Flock faces simultaneous state-level contract losses and federal legislative pressure. Employee buyout offers announced in September indicate internal headcount reduction ahead of revenue contraction.
