Federal Judge Rules Flock Safety Searches Unconstitutional Without Warrant

Another Win for Privacy Advocates

A federal judge in Oklahoma just handed down a significant ruling that could reshape how law enforcement uses automated license plate readers. Judge Sara Hill determined that a Tulsa sheriff’s deputy violated a woman’s Fourth Amendment rights by searching the Flock Safety database without a warrant, marking one of the first times a federal court has deemed such a search unconstitutional.

The case itself is fairly straightforward on its surface. The deputy searched Flock’s database for the woman’s license plate, apparently based solely on the fact that she had a California license plate. That search then provided the justification for pulling over and searching her vehicle, where officers allegedly discovered 91 pounds of methamphetamine. But Judge Hill wasn’t interested in the ultimate outcome. She focused instead on the process, ruling that all evidence obtained after the Flock search “must be suppressed as the fruit of a poisonous tree.”

The Broader Surveillance Problem

What makes this ruling particularly significant is Hill’s broader critique of warrantless tech surveillance. She wrote that tracking people’s movements, even in public, becomes “constitutionally problematic when law enforcement can indiscriminately and passively catalog your whereabouts over an extended period of time and then use that information for any purpose whenever convenient.”

Hill essentially called Flock what privacy advocates have been calling it for years: mass surveillance. Not targeted surveillance of a specific person, but an indiscriminate system that collects information on every vehicle passing any network-connected camera at all times, then makes that data available to cops on demand. That’s a crucial distinction that separates this from earlier Supreme Court cases on location tracking.

The ruling doesn’t create binding precedent outside Oklahoma, but it arrives at a moment when Flock is already facing pressure from multiple directions. State and local governments across the country, including Florida and Texas, have announced they’re ending their relationships with the company. Senator Bernie Sanders introduced the Block Flock Act on Friday, which would prohibit federal agencies from using automated license plate readers entirely.

Flock’s Reckoning

Flock CEO Garretty Langley has responded by calling for a “compromise” between privacy and safety, apologizing specifically to women stalked by law enforcement using Flock technology. Meanwhile, the company has offered voluntary employee buyouts as a way to reduce its workforce in response to all the cancellations. These are the kinds of moves a company makes when things are unraveling fast.

The irony here is thick. Flock positions itself as a tech tool to help law enforcement catch criminals and keep communities safe. But this Oklahoma ruling, along with the political and institutional backlash, suggests that the community’s definition of safety might include protection from being tracked without cause.

When you can be flagged in a system simply for having out-of-state plates, and that flag can serve as the pretext for further searches, we’re not talking about targeted law enforcement anymore. We’re talking about a system that treats everyone as a suspect until proven otherwise.

Judge Hill’s language matters here too. By explicitly calling this “indiscriminate mass surveillance,” she’s using terminology that resonates beyond law enforcement circles. It’s the same language privacy advocates use when discussing government overreach. And she’s right. The moment law enforcement doesn’t need a specific reason to search your travel history, only the ability to retroactively justify the search after finding evidence, the warrant requirement becomes theater.

What’s unclear now is whether other courts will follow Hill’s lead, or whether this ruling remains a lonely voice in the judicial wilderness. But given the momentum building against Flock, it seems increasingly unlikely that the company will maintain its current trajectory without significant changes to how its system operates and who can access it.
