20 Billion Scans a Month: Senate Opens Probe Into Flock's Plate-Reader Network

20 billion. That is roughly how many vehicle movements Flock Safety's camera network scans every month, a volume so large it means the daily driving of tens of millions of Americans can be logged, stored and searched by one private company ⁴⁶⁷². The system runs on roughly 120,000 AI-powered cameras nationwide ⁴⁶⁷². No public highway project created it. No Congress voted that number into being. It was built contract by contract, camera by camera, until it became something the country has never quite had before.

On August 26, 2026, Sen. Josh Hawley, Republican of Missouri and chair of the Senate Judiciary Subcommittee on Crime and Counterterrorism, opened a formal investigation into that network ²⁸¹⁰. In a letter to Flock Safety CEO Garrett Langley, Hawley demanded documents and answers by September 8 ²⁸¹⁰. The inquiry sits inside the Subcommittee on Crime and Counterterrorism ⁸.

At the center of the letter is a phrase Hawley's office uses to describe what Flock has assembled: an "unprecedented national surveillance network" ²⁴⁵¹⁰. The investigation asks what safeguards, if any, protect Americans' data inside a system of that size ²⁴⁵¹⁰. Hawley requested all documents on Flock's "collection, retention, and dissemination" of data ¹⁰. That three-word demand is the whole fight in miniature: what is taken, how long it is kept, and who gets to see it.

Hawley's stated rationale is not abstract. Just The News reports the senator pointed to "incidents of alleged police misuse of Flock cameras and arrests made based on false positive matches" ⁸. Two days after the letter, in an August 28 op-ed in The Daily Wire, Hawley argued that Flock's data collection "poses privacy threats and potentially violates existing laws" ⁶. Taken together, the letter and the op-ed frame the probe as both a civil-liberties question and a law-enforcement question: whether tools sold to find stolen cars and suspects are also creating new risks of error and abuse.

That argument is landing in cities already reconsidering the cameras. Ars Technica reports cities terminated Flock contracts "at record pace" in August 2026, citing data from a Bay Area anti-surveillance advocacy group ¹¹. Fox News reports Texas cities cut cameras over privacy and data fears ³. Gizmodo describes the moment as a national backlash sweeping the country ⁷. The Senate investigation did not start that local revolt, but it gives it a national address.

There is a reason scale is the opening fact rather than a detail. A network that scans about 20 billion vehicles per month is not merely a larger version of a neighborhood camera ⁴⁶⁷². At roughly 120,000 cameras, it can connect movements across towns, counties and states in ways no single police department could do alone ⁴⁶⁷². That is what Hawley's letter means by unprecedented: not that police have never used cameras, but that no single private network has held this much location history in one searchable place ²⁴⁵¹⁰.

The oversight question follows directly. Hawley's inquiry asks what rules govern that history and who enforces them ²⁴⁵¹⁰. The company sets retention periods, access controls and sharing defaults. Local agencies set their own policies on top. Congress has not written a dedicated statute for a private, nationwide plate-reader system. So the Senate is now asking, in effect, whether internal policies and thousands of local contracts are enough to protect data generated at a rate of billions of scans per month.

Flock's defenders would say the cameras solve real crimes, and Hawley's own subcommittee title — Crime and Counterterrorism — underscores that police agencies bought these systems because they wanted faster leads ⁸. But the terminations reported in August suggest many city councils no longer see the trade as automatic ¹¹³. Privacy fears and worries about where data flows were enough for Texas cities to pull cameras and for other cities to walk away at what Ars Technica called a record pace ¹¹³. Gizmodo's broader backlash framing captures the political danger for Flock: opposition is no longer confined to longtime surveillance critics ⁷.

September 8 is the first hard test. Hawley asked for all documents on "collection, retention, and dissemination" by that date ¹⁰. That production, if it happens, will show far more than marketing language: how long location records are actually kept, who can query them, what audits exist, and what happens when data moves between agencies ²⁴⁵¹⁰. Until then, the public record is mostly shape without texture — we know the network is vast and the Senate is demanding answers, but not what the internal files will reveal.

The second test is what the Senate does with whatever arrives. An investigation housed under the Subcommittee on Crime and Counterterrorism can become hearings, legislation, referrals, or nothing much at all ⁸. Hawley's op-ed language about potential violations of existing laws points toward a legal theory still to be spelled out ⁶. The cities that already cut ties will be watching whether Washington supplies a standard to replace the patchwork they just rejected ¹¹³.

The number that opened this story is still the number that matters. Twenty billion scans a month means driving itself has become searchable ⁴⁶⁷². Roughly 120,000 cameras mean that search spans the country ⁴⁶⁷². Hawley's probe will not decide by itself whether that is safety or surveillance. But by forcing Flock to document its collection, retention and sharing under Senate scrutiny, it will at least force an answer to the question cities are already asking with their cancellations: what safeguards protect Americans when the network never blinks ¹⁰²¹¹³.
