Flock Safety

Police are using license plate reader networks, from companies like Flock Safety and Axon, to flag cars by travel pattern and pull them over. Gizmodo cites a California grandmother quizzed about casino visits and a Wisconsin-Michigan driver stopped for repeat trips. A Texas jury sided with a driver flagged after one overnight trip.

The thread's best argument was about whether any of this can be audited.

Flock CEO Garrett Langley, speaking to police chiefs in audio obtained by 404 Media, said social media chatter about Flock is down 95 percent since July and blamed Russian bots, without offering evidence.

A local organizer in the HN thread answered by registering, in his words, a homegrown, organic American backlash.

Savannah police fired officer Amber Harpe in August after an investigation found she let her husband, an ICE agent, use her Flock license-plate-camera account. Local reporting counts nearly 1,000 searches across six states, mostly on Hispanic-owned vehicles.

Harpe argued firing was excessive because her husband is a federal officer. The thread's reply: that's exactly the problem.

The layer includes Motorola's Vigilant, Genetec, Axis, Axon, Leonardo's ELSAG, Neology, Rekor, PlateSmart, Ubicquia and Verkada. Engadget does not say where the locations come from or how many are mapped.

404 Media reports that police used Flock’s license-plate-reader network in a case connected to a pretextual weed search. The thread focused on the power created when widespread cameras make a person’s route searchable across jurisdictions.

Readers disputed the facts and the law of the specific stop, but converged on the broader risk: surveillance data lowers the cost of finding a reason to intervene, while the consequences of a mistaken stop fall heavily on the person stopped.

The test case is Schmidt v. City of Norfolk, over the city's roughly 175 plate-reading cameras. A January 2026 district court sided with Norfolk, ruling its 21-day data retention too short to count as a search; the appeal now has 15 states lined up behind the city.

One close reader warns the article oversells: Chatrie's private-location logic has "almost no analog" in third-party recordings of public movement.

Engadget reports there are now over 100,000 Flock cameras in the US, running modified Android, feeding a searchable network where a Texas officer can query Massachusetts footage and ICE rides along through local police. Searcher Benn Jordan found 70-plus cameras streaming live, password-free, in December 2025.

Then an HN commenter who co-led the campaign that removed Flock from Eugene and Springfield, Oregon and helped draft state ALPR law said his team decompiled a device: the object-detection categories included 'cat,' 'dog,' 'person,' 'bicycle' — confirming from the binary what marketing implies.

IPVM counts at least 18 documented cases of police using license-plate readers to track partners or rivals, including a Sedgwick, Kansas chief who queried an ex-girlfriend's plate 164 times and a Holiday Hills chief who tracked one man up to 178 times. Flock's Chief Legal Officer Dan Haley called such stalking "actually the most common thing" while also calling it rare. A commenter defended him: rare overall and most-common-among-abuses are logically compatible.

A Flock camera photographed a red Alfa Romeo — real car, wrong plate, geometrically impossible location. The victim's clothing description didn't match either. Police arrested two men anyway.

Parra and Beltran each seek $1.5 million. Their tort claim: other Flock cameras along their actual route would have cleared them instantly. Nobody checked.

tptacek's reversal: this isn't a Flock failure, it's SDPD treating a color-match as probable cause. The exonerating data was in the same system.
