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).

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).

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)).

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.
