US federal judge rules warrantless Flock licence-plate search unconstitutional
What happened? In early October 2026 a US federal judge, Sara Hill, ruled that a Tulsa, Oklahoma sheriff's deputy violated a woman's Fourth Amendment rights when he used Flock Safety's automatic licence-plate reader (ALPR) network to search for her plate without a warrant. The deputy had "no apparent reason" for the search "other than the fact that [the woman's vehicle] had a California licence plate"; he later used her travel history in Flock to help justify a search of her car, where he is alleged to have found 91 pounds of meth. Judge Hill ordered the evidence suppressed "as the fruit of a poisonous tree".
Why it matters: The ruling does not set binding precedent, but it is one of the first times a US federal judge has held a Flock search unconstitutional. Judge Hill wrote that tracking people's location, even in public, becomes "constitutionally problematic when law enforcement can indiscriminately and passively catalogue your whereabouts over an extended period of time", and described the network as "a type of indiscriminate mass surveillance". The decision lands as scrutiny of Flock intensifies: Florida and Texas have moved to block Flock cameras over privacy concerns, several local governments have cancelled or restricted deployments, and on 2 October 2026 Senator Bernie Sanders introduced the Block Flock Act to bar federal agencies from using automated licence-plate readers such as Flock. Flock chief executive Garrett Langley has called for a "compromise" between privacy and safety.
