Judge Rules Deputy's Warrantless Flock Search Violated Rights

A federal judge in Oklahoma ruled this week that a Tulsa County sheriff's deputy broke the Fourth Amendment when he searched the Flock Safety license plate database for a woman's car without a warrant, according to TechCrunch, which cited reporting from 404 Media. The ruling does not set binding precedent for other courts, but it is one of the first times a federal judge has called a Flock search unconstitutional outright.

Here is what happened, in order, and what it means for drivers and police departments that use the cameras.

What did the deputy do, and when?

The deputy ran the woman's license plate through Flock's network of automated camera readers. Judge Sara Hill wrote he had "no apparent reason" for the search "other than the fact that [the woman's vehicle] had a California license plate," TechCrunch reported. The deputy then used her travel history pulled from Flock as part of his justification for pulling over and searching her car. That search allegedly turned up 91 pounds of methamphetamine, according to the TechCrunch account.

What did the judge rule this week?

Judge Hill ruled the Flock search itself required a warrant the deputy never got. Because the search was unconstitutional, she ordered that everything found afterward — including the drugs — be thrown out. "Fruit of the poisonous tree" is the legal term she used, per TechCrunch, meaning evidence gathered as a direct result of an illegal search cannot be used in court.

Hill did not stop at the single search. 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." Her sharpest line, quoted by TechCrunch: "This is a type of indiscriminate mass surveillance."

How is this different from the Supreme Court's cellphone tracking case?

Hill drew a direct contrast with Carpenter v. United States, the 2018 Supreme Court decision that limited how police access cellphone location data. In that case, she noted, surveillance was targeted at a single suspect. Flock, by contrast, "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," TechCrunch reported her writing. That distinction — targeted surveillance versus blanket collection — is the legal hinge the rest of the ruling swings on.

What has happened around Flock this same week?

The ruling landed in the middle of a broader run of bad headlines for the company, based on the same TechCrunch report:

• Several state and local governments, including Florida and Texas, have said they will stop using Flock's automated license plate readers.
• On Friday, Sen. Bernie Sanders introduced the Block Flock Act, which would bar federal agencies from using automated license plate readers like Flock's.
• Flock CEO Garrett Langley has called for a "compromise" between privacy and public safety and apologized to women who were stalked by law enforcement officers who misused the Flock system, TechCrunch reported. Langley is scheduled to be interviewed on stage at TechCrunch Disrupt.
• Flock has reportedly offered employees voluntary buyouts as the company looks to shrink its workforce amid the cancellations.

Does this ruling stop police from using Flock everywhere?

No. Judge Hill's decision applies to this one case in the Northern District of Oklahoma and does not bind judges in other states or federal circuits, TechCrunch noted. Police departments elsewhere can keep using Flock the way they have been unless a court with authority over them rules otherwise, a state legislature acts, or Congress passes something like Sanders' bill. But defense attorneys in other jurisdictions now have a federal ruling they can cite when challenging warrantless Flock searches tied to criminal cases.

What changes for drivers and departments right away?

For drivers in Tulsa County, nothing changes in terms of the cameras themselves — they keep scanning plates. What changed is the legal risk for officers who search that database without a warrant and then use the results to justify a stop or search. Any case built that way in this district is now vulnerable to the same "fruit of the poisonous tree" argument that got the 91 pounds of meth excluded here.

For departments that already dropped Flock, like those in parts of Florida and Texas, the ruling adds legal weight to decisions made on cost or policy grounds. For departments still using it, the ruling is a warning sign: a federal judge has now put in writing that pulling a plate's travel history without a warrant can taint everything that follows.
