One photo of your car on a public road is just a photo. Fifty of them across several states, stapled together by a police database, is a flipbook of your week, and a federal judge in Oklahoma just said an officer needed more than a hunch to start flipping.
In an order dated October 1, U.S. District Judge Sara Hill ruled that a Tulsa County deputy's warrantless search of license-plate-reader systems, including Flock, was unconstitutional. According to TNW, citing 404 Media, the deputy ran the search only because the car had a California plate. It turned up more than 50 sightings of the driver's vehicle across several states, which then became part of the reason the car got searched. The judge threw out the evidence and described Flock's network as "a type of indiscriminate mass surveillance."
Some background on why that sentence matters. Flock's network, which the Washington Post reported in August at roughly 120,000 cameras, photographs license plates and vehicle details and logs where and when. Earlier courts have often said that's fine, since a car on a public road has no privacy to lose. The judge's logic, as reported, is the flipbook problem: one sighting reveals nothing, but strung together they reveal where someone goes, and that's a different thing. Each sighting is one page. Flip slowly and it's boring. Flip fast and it's a movie about you.
Flock sees it differently. The company says the ruling goes against the overwhelming weight of similar cases, including recent Oklahoma decisions, is limited to the facts of this case, and doesn't change how police use its cameras. It expects the decision to be appealed and overturned. Worth knowing: a district court ruling doesn't bind other courts, and 404 Media notes it's one of the first times a federal judge has found a Flock search unconstitutional. So this is either a landmark or a footnote, and an appeals court gets to decide which.
Lawmakers are paying attention either way. In September, two House members introduced the No FLOCK Act, a name doing a lot of work, and TNW reports Florida and Texas have moved against the cameras too.
When we covered Flock in August, the story was officers misusing the network to look up people they knew. This is a different question about the same system: not whether an officer broke the rules, but whether the rules, as written, let police do this at all without a warrant. That part isn't a joke. It's just the part worth remembering.
Meanwhile, somewhere in Oklahoma, a California license plate has become the most legally significant rectangle in the state.
