Flock Safety

Flock Safety is a US company that sells computer-vision surveillance systems to law-enforcement agencies and private customers, built around automatic license plate readers (ALPRs) whose captured plate data is searchable across a shared network of camera deployments. It was founded in 2017 by Garrett Langley and Matt Feury and is headquartered in Atlanta, Georgia; Langley is chief executive. Langley has said the company originated after he experienced a property crime in Atlanta that police could not act on for lack of evidence (Source: sacra.com).

Flock is the leading vendor of AI-augmented ALPRs to US municipalities, with more than 5,000 deployments as of 2024 according to public reporting (Source: s2.washingtonpost.com). Its products are a commercial instance of the pattern described on AI and Surveillance: cheap continuous inference over public camera feeds tightens the effective surveillance regime without any formal change in law.

Products

Flock's core product is a fixed ALPR camera whose captured plate reads are pooled into a network searchable by participating agencies. Around that core it has added natural-language search and compliance tooling.

FreeForm is a natural-language search interface over the camera network. Network-audit data reviewed in July 2026 showed police departments using it at least hundreds of times to search for people rather than vehicles — the California Highway Patrol searching 274 cameras for a "gray shirt," the Texas Department of Public Safety querying 96 camera networks, Milford (CT) police searching more than a hundred cameras for a "male with tattoos," and Anne Arundel County (MD) police querying 198 networks for a "white jeep with trump flag." Some searches referenced race despite a stated guardrail barring attribute searches on race, ethnicity, religion, or nationality. Flock said FreeForm "is not facial recognition" and that it has no facial recognition in development (Source: 404media.co). The deployment is described in more detail on Surveillance Technology.

Audit Assistance flags what the company calls "abnormal search behavior" and locks out the flagged user until an administrator reviews the activity. It launched as a voluntary feature in April 2026 and, as of August 2026, had been enabled by only about a third of the agencies working with Flock (Source: theverge.com).

Evidence Mode, introduced in August 2026, preserves searches tied to a specific case number beyond the default retention period (Source: theverge.com).

OS Investigate, an AI tool for police originally called Nightshift, identifies drivers and tracks vehicles by movement patterns alone. WIRED reported on August 19, 2026 on the product's design as reconstructed from more than 450 files served by Flock's own login pages: the system ships with 69 prewritten prompts and 45 tools reaching plate scans, arrest records, dispatch logs and commercial databases, and 14 of the prompts require no plate, name or description to run. Its "associates" ranking counts plates that appear at the same cameras within a two-minute window at least three times, at a default confidence threshold of 0.75. Flock spokesperson Paris Lewbel said the product is separate from the company's license plate readers and that its capabilities may change before broader release (Source: wired.com).

Misuse reporting and the August 2026 policy change

A series of reports through 2026 documented police officers using Flock's network for personal purposes. The Washington Post reported on August 2, 2026 that a police chief in Braselton, Georgia had searched his ex-girlfriend's license plate more than 500 times over seven months. California prosecutors alleged that a former Riverside County Sheriff's Office deputy used Flock data to stalk and harass an ex-girlfriend, looking up plate information on men she was dating. The Institute for Justice has documented ALPR abuse reports dating to 2021, identifying at least fourteen instances in recent years (Source: theverge.com).

On August 13, 2026 Langley told The Verge that the company would change course, saying of the case-code requirement, "This is such an obvious way to curb abuse… And I said, 'Fine. You know what? I think that's right, and we got this one wrong. We should make it a requirement.'" The changes, to be implemented over subsequent weeks, are:

• Audit Assistance becomes mandatory for all agencies rather than optional.
• Case codes required on every search. An administrator may override the requirement for emergencies such as tracking a missing child, but overrides are automatically flagged for review.
• Default retention cut from 30 days to seven for data from devices including ALPRs. Departments may still choose to lengthen the period.
• Granular inter-agency sharing. Localities could previously share data with other agencies only on an all-or-nothing basis; they can now permit, for example, another department to search their Flock data for a homicide suspect while withholding access for immigration enforcement.

Langley framed the shift as a change in his view of where responsibility sits. He had previously argued that lawmakers rather than the vendor should set guardrails, and said he now accepts that the regulatory process moves too slowly for that position to hold, while still preferring that legislators make the key calls — a preference he acknowledged is not entirely disinterested, since binding rules would also force competitors to adopt similar controls. He predicted that "you are going to see more officers fired and more officers arrested for abusing police power," and said an internal July 2026 update recorded the network helping find almost a thousand missing people and more than 22,000 stolen cars in that month alone (Source: theverge.com).

The American Civil Liberties Union published an analysis after the announcement concluding that the changes appear "more focused on addressing a perceived PR problem than the significant harms its products create." It called the shorter retention period a potential "step in the right direction" while noting that the practical effect depends on how Evidence Mode is implemented, and asked for independent review of the auditing and search-reason tools to establish how effective they are (Source: theverge.com).

Senate Judiciary investigation (August 2026)

A letter dated August 26, 2026 from Senator Josh Hawley (R-Mo.), chairman of the Senate Judiciary Subcommittee on Crime and Counterterrorism, to chief executive Garrett Langley opened an investigation into the company's "collection, retention, and dissemination of the data generated by its artificial intelligence surveillance cameras." Hawley's stated ground is the absence of a statutory basis for the network: Congress "never authorized the network your industry has built," he wrote, adding that "your company's internal policies are, in practice, the only safeguards for hundreds of millions of Americans." The constitutional anchor is Carpenter v. United States, 585 U.S. 296 (2018), cited for the proposition that a comprehensive, retrospective record of a person's movements "is different in kind from ordinary observation in public." The objection is to aggregation: rather than "serving discrete local investigations, as contemplated by our constitutional processes and safeguards, these camera networks harness artificial intelligence to pool what they capture into a national database that customers can search" (Sen. Josh Hawley, letter to Flock Safety CEO Garrett Langley (August 26, 2026)).

The letter's factual predicate is five incidents, each footnoted to public reporting: the St. Charles County, Missouri police department's termination of its contract in August 2026 after an audit found a civilian employee running searches for personal reasons; the Milwaukee officer charged after allegedly searching his girlfriend's plate 124 times and her former boyfriend's 55 times, entering "investigation" as the justification each time and detected not by Flock's audit systems but by a private citizen looking up his own plate; the Florida woman who spent 13 days in jail facing eight felony counts including three of vehicular homicide after an arrest based on a Flock vehicle-description search, with charges dismissed seven months later; a California police department that found 71% of its alerts wrong; and the Los Angeles Police Department's decision to drop its contract after an audit showed 161 vehicles incorrectly stopped as stolen within two months. Hawley also cites the company's $8.3 billion valuation as bringing "enormous pressure to find new commercial applications" (Sen. Josh Hawley, letter to Flock Safety CEO Garrett Langley (August 26, 2026)).

The letter demands documents on law-enforcement access, camera placement and data handling; a list of any known or suspected misuse of Flock systems since 2021; files on camera accuracy and security; and the company's contracts with local governments, revenue sources, and investors. The misuse list overlaps directly with the reporting policy Flock changed earlier in August 2026, described above. Spokesperson Paris Lewbel said the company had received the letter and would respond directly. Flock's own figures put the network at 120,000 cameras and state that it has aided roughly 1 million police investigations and helped find around 10,000 missing people; those figures are the company's and are not independently audited (Source: axios.com).

The three-page annex sets the Relevant Period at January 1, 2021 to the present and defines "Flock" to reach each product line by name — Flock OS, Flock Nova, Falcon, Sparrow, Raven, Condor and Aerodome — as well as any third party from which Flock "has the practical ability to obtain" documents, including cloud service providers. Ten interrogatories ask, among other things, whether statewide and nationwide search is enabled by default; the default retention period for each data category and every change since 2021; the total number of confirmed misuse instances by year and whether each was first identified by Flock's own monitoring, the customer, or a third party; whether the search-justification field is validated against any external record and whether a search proceeds when it is left blank or filled with generic text such as "investigation"; measured accuracy "at the level of a complete and correctly attributed vehicle identification"; every data category the devices capture including audio, wireless signals and biometric identifiers; whether Flock has "ever ingested, licensed, evaluated, or tested data obtained from a security breach"; and whether the company has the capability to track individuals biometrically.

Twelve document requests cover the same ground plus the treatment of "derived data such as vehicle fingerprints or model embeddings," whether audit records are "complete, immutable, and exportable," sharing with federal agencies, foreign governments, private entities and data brokers, "access to production systems by personnel or contractors located outside the United States," the use of customer or third-party data to train Flock's models, and investors holding more than 5% of any class of equity together with lobbying expenditures and political contributions. Production is due September 8, 2026 (Sen. Josh Hawley, letter to Flock Safety CEO Garrett Langley (August 26, 2026)).

Criticism and vendor pushback

The ACLU and the Electronic Frontier Foundation have accused Flock of misleading the public and officials about the risks of its tools, and have warned the network could be used to track women seeking abortions. Flock has said officers are prohibited from running searches related to reproductive care in states where such searches are restricted, and in at least one instance attributed a disputed statement to confusion over a nuanced issue (Source: theverge.com).

Langley's posture toward critics has shifted over the same period. In a September 2025 Forbes interview he described DeFlock — a project mapping Flock deployments across the country — as a "terroristic" group; in July 2026 he apologized and called the characterization a "mistake" (Source: theverge.com).

Municipal deployments have produced local political conflict and at least one large contract loss. Washington Post coverage in May 2026 reported that Flock cameras in Troy, New York had divided the town and contributed to a state of emergency (Source: s2.washingtonpost.com). The Los Angeles Police Department let its Flock contract expire over the weekend ending July 13, 2026 — the largest US police department to drop the vendor — after an audit found the department had improperly investigated 161 people in a two-month period whose cars were wrongly flagged as stolen by the readers (Source: 404media.co). Both cases are covered on AI and Surveillance.

Flock was one of at least 21 companies mapped by Ranking Digital Rights in July 2026 as building surveillance infrastructure across the sixteen 2026 World Cup host cities, and one of five the report identified as already embedded with host-city law enforcement before the tournament (No Fair Play: Mapping the 2026 World Cup Surveillance Stack (Ranking Digital Rights, July 2026)).

Texas state funding pause (August 2026)

Texas Governor Greg Abbott ordered state agencies on the night of 27 August 2026 to pause funding for Flock cameras, his spokesman confirming the order on 28 August as The Texas Tribune prepared to publish an investigation finding that a state agency had devoted at least $30 million to building the state's Flock network. The Motor Vehicle Crime Prevention Authority, whose board is mostly appointed by Abbott, has helped install at least 3,200 Flock cameras since 2023, almost 1,200 of them by the Department of Public Safety under a three-year, $15.9 million contract; the grants came from a 2023 law that added $1 to Texas auto insurance policies to combat catalytic converter theft. Abbott spokesperson Andrew Mahaleris said agencies "are clarifying that those funds cannot be used for Flock cameras" (Source: texastribune.org).

The order followed misuse cases in the state. A Lufkin police officer faces 100 counts of misusing public information for allegedly using the area's cameras to surveil 11 people for more than a year, and at least six Texas departments in the month to 28 August 2026 placed officers on leave, opened investigations or brought charges. Flock Safety said it supports "thoughtful legislation" with privacy guardrails (Source: texastribune.org).

The funding pause is a procurement-side constraint imposed by a state executive rather than a legislative or judicial one, and it operates on the grant stream rather than on the cameras already installed. See State-Level AI Regulation and Surveillance Technology.

Electoral politics and federal legislation

Flock became a campaign issue in the 2026 midterm cycle. Abdul El-Sayed, the Democratic nominee for Senate in Michigan, posted a video to X on August 19, 2026 tying his Republican opponent, former Rep. Mike Rogers, to Flock's license plate reader cameras. Sen. Bernie Sanders wrote on August 18, 2026 that "Flock has installed nearly 100,000 cameras across America to track your every movement." A trio of House Republicans led by Rep. Tim Burchett introduced H.R. 9800 in the 119th Congress to bar the federal government from purchasing Flock cameras or similar technology. Flock says its cameras have aided roughly 1 million police investigations and helped find around 10,000 missing people, and has said it is improving its privacy features (Source: axios.com).

Available figures for the network's size disagree: Sanders put it at nearly 100,000 cameras, while the same reporting puts it at 120,000. Neither figure is independently confirmed here. See AI Backlash, AI in Elections and Democratic Institutions.

Open questions

• Whether the mandatory Audit Assistance and case-code requirements measurably reduce misuse, which the ACLU has asked be established by independent review rather than by vendor assertion.
• Whether the seven-day default retention holds in practice, given that departments retain the option to lengthen it and that Evidence Mode preserves case-linked searches indefinitely.
• Whether other ALPR vendors adopt comparable controls, which Langley has said he expects the changes to pressure them toward.
