Judge Rules Flock License Plate Search Was Unconstitutional Surveillance
A federal judge suppressed drug trafficking evidence after finding a deputy's warrantless search of Flock Safety's nationwide database violated the Fourth Amendment.
Key takeaways
- U.S. District Judge Sara E. Hill ruled that warrantless searches of Flock Safety's license plate database amount to 'indiscriminate mass surveillance' and violate the Fourth Amendment.
- The decision suppressed 91 pounds of methamphetamine found during a traffic stop because the officer's initial search of the suspect's travel history lacked probable cause.
- Flock stated that it was not a party to the case, argued the decision conflicts with existing precedent, and expects the ruling to be appealed.
- The ruling comes alongside growing legislative scrutiny, including federal bills proposed by lawmakers to restrict or ban automated license plate readers.
A federal judge in Oklahoma has ruled that a police officer's warrantless search of Flock Safety's automated license plate reader (ALPR) database violated the Fourth Amendment, calling the nationwide camera network a form of "indiscriminate mass surveillance." The decision marks one of the first times a federal court has determined that querying Flock's historical vehicle tracking data requires a warrant.
The ruling, issued by U.S. District Judge Sara E. Hill, suppresses all evidence gathered during a May highway stop that yielded 91 pounds of methamphetamine, as detailed by 404 Media. While the decision does not set binding nationwide precedent, it challenges the long-standing legal framework that law enforcement agencies rely upon to run more than a hundred thousand warrantless ALPR searches every month.
Highway Stop and the Flock Database Query
The case stems from an incident in Oklahoma involving Tulsa County Deputy Sheriff Freddie Alaniz, who observed a Mazda SUV bearing California plates driven by Melisa Kyle. Alaniz followed the vehicle and ran Kyle's license plate number through Flock's AI-powered database solely because the car displayed out-of-state tags, according to court findings reported by 404 Media.
After pulling Kyle over for changing lanes without a turn signal, Alaniz questioned her while reviewing the database results. The search revealed more than 50 historical records tracking Kyle's vehicle across the country over a 30-day span. Alaniz pointed to Kyle's short stay in California as justification to search her SUV for suspected narcotics trafficking. In her ruling, Judge Hill held that using Flock to reconstruct a driver's historical movements without probable cause was an unconstitutional warrantless search, making all subsequent evidence inadmissible as "fruit of the poisonous tree," according to TechCrunch.
Dragnet Surveillance vs. Public Privacy Expectations
Prior judicial decisions permitting warrantless ALPR searches often cited the Supreme Court's 1983 decision in United States v. Knotts, which established that individuals have no reasonable expectation of privacy when traveling on public roads. However, Judge Hill distinguished modern networked cameras from 1980s tracking beepers, writing that older legal tests did not contemplate automated systems capable of tracking entire populations continuously.
"The Court acknowledges that people, in at least a broad sense, do not have a reasonable expectation of privacy in their movements on a public roadway," Hill wrote. "But by virtue of how ALPR technology works, Alaniz and other officers using these systems have access to a continuously updated location history for all vehicles caught on ALPR cameras within the network. This is a type of indiscriminate mass surveillance. It is not targeted on a single individual, as in Carpenter. It is a tool that collects information about all vehicles that pass by any network-connected camera at all times, and it serves up the information to law enforcement on demand."
Legal advocates welcomed the decision. Michael Soyfer, an attorney at the Institute for Justice, told 404 Media that the ruling acknowledges "the sheer breadth of these systems, that they collect so much information about so many people in a way that sets them apart."
In response, a Flock Safety spokesperson stated that the company was not a party to the lawsuit and maintained that the decision would not alter broad policing practices. "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 told 404 Media. "This ruling is limited to the specific facts of this case. It does not set controlling precedent and does not affect law enforcement agencies’ continued use of these important public safety technologies."
Growing Scrutiny and Federal Legislative Action
The Oklahoma decision coincides with mounting political and civic resistance to mass vehicle surveillance. In Michigan, residents gathered in Milford to protest municipal deployments of Flock hardware, reported The Washington Post, while several local and state jurisdictions, including Florida and Texas, have announced plans to discontinue using the technology, according to TechCrunch.
Lawmakers in Congress have also escalated oversight efforts. Senators Bernie Sanders and Jeff Merkley, along with Representative Alexandria Ocasio-Cortez, introduced legislation dubbed the Ban Flock Act to prohibit federal agencies from utilizing ALPR systems and cut off related federal grants, as reported by Mashable and TechSpot. In the House, Florida Representative Greg Steube previously introduced a separate measure requiring law enforcement to obtain warrants before searching ALPR databases.
Flock CEO Garrett Langley has acknowledged privacy concerns, calling for balance between safety and privacy while offering voluntary employee buyouts amid regional cancellations, reported TechCrunch. With federal judges beginning to question the constitutional limits of historical tracking data, the legal status of automated surveillance networks faces intensified review across the judicial and legislative branches.
