A federal judge in Oklahoma suppressed drug evidence after ruling a deputy’s warrantless Flock camera pull of a month of driver location data violated the Fourth Amendment, and the company says it will appeal.
Daily Caller reported that U.S. District Judge Sara E. Hill granted defendant Melisa Kyle’s motion to suppress in a Northern District of Oklahoma drug case. Hill found the warrantless search of automated license plate reader data from Flock’s camera network unconstitutional.
Tulsa County Deputy Freddie Alaniz began trailing Kyle’s Mazda SUV for no reason beyond its California plate, according to the ruling. He queried the Flock system for her plate before he observed any traffic violation.
The system logged her car more than 50 times across multiple states in a single month. That reconstruction of a full month of movements carried no warrant and no probable cause.
Hill upheld the traffic stop as valid at its start. But she ruled Alaniz lacked reasonable suspicion to keep holding Kyle after he returned her license. The extended detention became unlawful.
Reconstructing a month of Kyle’s travels breached her reasonable expectation of privacy. The judge granted the motion and threw out the drug evidence that followed from the stop.
Hill’s order did not outlaw the technology outright. It targeted the warrantless use of the network to build a detailed travel history.
"a type of indiscriminate mass surveillance"
That is how the judge described the practice in her opinion. She added a clearer line on what drivers can expect.
"Freedom from persistent, dragnet-style surveillance while in public is not a foreign concept in our society, and it is a reasonable expectation that society already accepts,"
The ruling lands amid wider pushback against the same camera networks. Texas Gov. Greg Abbott and Florida Gov. Ron DeSantis each moved over the past two months to restrict Flock.
Several local governments have already canceled their contracts. One example came when a Knox County mayor halted a $1 million Flock deal over the same Fourth Amendment concerns.
Flock was not a party to the criminal case. A company spokesperson still rejected the decision and framed it as an outlier.
"The ruling goes against the overwhelming weight of authority in similar cases across the country, including multiple recent decisions in Oklahoma, and we expect it will be appealed and ultimately overturned,"
The spokesperson said the order sets no controlling precedent. Flock expects higher courts to reverse it.
On October 3, 2026, the account SCOTUS Wire posted a summary of the same holding: police violated the Fourth Amendment by searching Flock and other license plate reader data without a warrant and accessing more than 50 records of a driver’s movements across multiple states over a month.
Concerns about misuse are not new. Flock Safety overhauled its cameras after officers used them to stalk women and spy on exes, showing how the same tools can leave the traffic-stop lane.
Sens. Bernie Sanders and Jeff Merkley and Rep. Alexandria Ocasio-Cortez introduced legislation to bar federal agencies from using the systems. Their bill would also freeze federal grants that help local police buy the technology.
That effort sits alongside unfinished business on the Hill. Lawmakers have left broader surveillance reform on the shelf while heading home early, even as camera networks spread.
Public frustration has turned physical in some places. A New Mexico man livestreamed himself ripping down surveillance cameras and then drove straight to the sheriff’s office, underscoring how visible the networks have become.
Automated license plate readers record plates and locations as cars pass fixed or mobile cameras. Police can query the database later to map where a vehicle has been. In this case the query came first, the traffic violation second, and a month of interstate hits filled the gap without a judge’s sign-off.
Hill’s decision keeps the cameras legal while drawing a hard line at warrantless historical tracking. Drug evidence is gone from this prosecution because the path to it ran through an unlawful detention and an unlawful data pull.
Warrants still matter on the open road. New cameras do not erase the Fourth Amendment just because they make a month of travel easy to reconstruct.
