US Judge Rules Police Flock Search Unconstitutional Mass Surveillance
A federal judge in Oklahoma has ruled that a deputy’s warrantless search of Flock’s license plate reader network violated the US Constitution, marking a potential game changer in the ongoing debate over privacy and technology.
The Ruling
On October 1, 2026, Judge Sara Hill issued an order stating that Flock's system amounts to "indiscriminate mass surveillance." She wrote,
"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."
The Case
The ruling stemmed from an incident where Tulsa County deputy Freddie Alaniz pulled over a driver, Melisa Kyle, after observing her following another car too closely. Upon checking her license plate through Flock, Alaniz discovered a pattern of short trips to California, which he suspected was connected to drug trafficking. He conducted a search and eventually arrested Kyle, leading to charges of possessing methamphetamine with intent to distribute.
The Judge's Decision
Hill ruled that both the extended stop and the Flock search were unconstitutional, suppressing all evidence gathered after the search began. She cited a 1983 Supreme Court case, United States v. Knotts, which allowed similar warrantless searches, but noted that Flock's capabilities were closer to a "dragnet" practice.
She also referenced a recent Supreme Court ruling in Carpenter v. United States (2018), which considered phone location records as a form of search, and a different case, Chatrie, which established that police access to phone location history constitutes a search.
Flock's Response
Flock, while not a party to the case, expressed disagreement with the ruling, stating:
"The ruling goes against the overwhelming weight of authority in similar cases across the country... and we expect it will be appealed and ultimately overturned."
Despite the ruling, Flock emphasized that it does not affect police use of their cameras, citing a recent federal appeals court decision in March 2026 that upheld the readers.
The Bigger Picture
The case highlights the ongoing tension between technological advancements and individual privacy rights. With police conducting over 100,000 warrantless Flock searches monthly, according to an audit, this ruling could have significant implications for law enforcement practices involving license plate readers.
