Overview
- A federal district judge found that a warrantless search of a month of automated license‑plate reader (ALPR) records violated the Fourth Amendment and ordered evidence obtained after the search suppressed.
- Court records show a Tulsa deputy followed a California‑plated Mazda, ran a query that returned more than 50 ALPR sightings across multiple states over roughly a month, and then stopped the driver for moving violations.
- The judge upheld the initial traffic stop but ruled the officer lacked reasonable suspicion to extend the detention, a sequence that contributed to the court toss of the case evidence that included 91 pounds of methamphetamine.
- In a written opinion the judge described broad, continuous ALPR collection as a form of ‘‘indiscriminate mass surveillance’’ and said historical, multi‑state location searches can require a warrant.
- The decision applies only to this district court case, is expected to be appealed, and arrives as Flock Safety’s large ALPR network, split court rulings, and congressional and contract reviews keep the technology under scrutiny.
