On October 1st, a federal judge in Tulsa, Oklahoma ruled that a sheriff's deputy's warrantless search of plate reader history was an unconstitutional search, and she threw out the evidence. Her name is Sara E. Hill. She sits in the Northern District of Oklahoma, and the opinion runs 38 pages.
I made 2 videos off it. The first one walks through the case and what it means for your town. The second is about how she got there, and why I think she deserves a crown.
Housekeeping. This one goes in this order: what happened, what she wrote, how to use it, the parts that cut against me, then where the document came from. If you hit reply, I read it.
What happened
The deputy works the highways around Tulsa, and the camera on his patrol car feeds plates into the network. One evening a car with California plates goes by. The judge writes that he followed it "for no apparent reason other than the fact that it had a California license plate."
While he followed it, he ran the plate through Flock and through a second system called VehicleManager. The reasons he typed in were "traffic violation" and "investigation." The judge found that at that point, all he knew was that the car had California plates.
What came back was a month of where that car had been, "more than fifty sightings across multiple states" in the opinion's words.
He pulled the car over for lane changes and wrote a warning. Then he asked to search it. She said no, so he held her there for a drug dog. The dog alerted, and she was arrested.
What she wrote
The government argued that the data is "in plain view on public roadways," so nobody has any privacy in it. That argument has been winning. The judge writes that "it appears that nearly every court examining the issue to date has determined that ALPR technology use is not a search," and that includes several other courts in Oklahoma.
She went the other way, and she got there through a 1983 Supreme Court case called Knotts, about a beeper hidden in a drum of chloroform. Knotts is where the "no expectation of privacy on a public road" line comes from. A couple pages later in that same opinion, the Court said that if dragnet type practices ever showed up, there would be time enough then to deal with them. Her answer is on page 31:
"More than 40 years have passed since the Supreme Court's decision in Knotts, and this Court is now faced with technology that appears to be approaching the dragnet type law enforcement practice Mr. Knotts warned of."
The lines I'd print and carry into a meeting:
Page 34. Nobody expects a stranger, "and especially not law enforcement," to walk up and say: "Hey, I have been following your car for the last 30 days, and here is a detailed log of every place your vehicle has been with supporting photographic evidence."
Page 35. "It is also no longer difficult to imagine law enforcement using a fleet of drones hovering over an entire city so they don't miss the movement of a single vehicle. This is not hypothetical catastrophizing."
Page 36. "It could track and log a couple struggling to start a family at the fertility clinic."
Page 37. "Why is it the government's business where everyone goes all the time?" And 2 sentences later: "It is not too much to draw the line at indiscriminate mass surveillance."
How to use it at your city council
Bring the case number and the page numbers: Case No. 4:26-cr-00189-SEH, Northern District of Oklahoma, ECF No. 62, filed October 1, 2026. Anybody with a PACER account can pull it.
Pick 1 line and read it out loud. Page 34 is the one that lands in a room.
Then ask questions they have to answer on the record. Does our department search plate reader history without a warrant? What gets typed into the reason box? Has the city attorney read this opinion?
Your city or county, if they're paying attention, should now be seeing its use of Flock or any other AI-tied license plate reader as a liability.
The parts that cut against me
It's 1 judge in 1 district, and it binds no other court. I'd bet the government appeals.
She threw the evidence out a second way too. Holding the driver for the dog without a good reason was a separate violation, so the evidence was out either way.
He searched 2 systems, Flock and VehicleManager, and the ruling covers the search in both.
I'm not a lawyer, and what the next judge does with it, I don't know.
Also out of Oregon
On October 5, 2 Oregon state reps, Willy Chotzen (D-Portland) and Alek Skarlatos (R-Winston), stood with Sen. Ron Wyden and announced they want a statewide ban on Flock cameras in the 2027 session. There's no bill text yet, so what it covers is still unknown.
The record behind this issue
1. Opinion and Order, Case No. 4:26-cr-00189-SEH (N.D. Okla.), ECF No. 62, Judge Sara E. Hill, filed October 1, 2026, 38 pages. Every quote in this issue was re-checked against the PDF text on October 8, 2026. The case name carries the driver's name, so I cite it by number. CourtListener has the docket indexed, but the opinion itself is PACER-only.
