Flock, the company that operates roughly 120,000 automatic license‑plate readers (ALPRs) across the United States, announced platform changes last Thursday intended to prevent officers from using its system for illegal or illegitimate purposes. The move follows reporting by The Washington Post that identified 50 cases in which officers misused systems from Flock and competitors, often to stalk and harass women. In one Wisconsin case a woman said her former police boyfriend searched for her car 179 times; in another, a woman was stalked by a police chief with no clear channel for complaints.
What did Flock change?
The company introduced practices designed to tie searches to legitimate purposes: software will flag abnormal query patterns, and officers must enter a criminal case number when initiating a search. Flock frames these measures as steps to reduce stalking and other abuses of the platform.
Where are the loopholes?
The announced policies leave important gaps. Flock confirmed to outside outlets that it does not verify the case numbers entered by officers, meaning a user can enter a bogus number — and accounts have already suggested officers have lied to circumvent previous Flock safeguards. Civil‑liberties and privacy groups say the measures do not address the broader structural choices that make Flock’s offering functionally a mass‑surveillance network rather than a narrowly targeted law‑enforcement tool.
Those criticisms have prompted pushback: some cities have canceled Flock contracts, some agencies have switched to competitors, and several U.S. states are considering laws to restrict or ban ALPRs altogether.
Questions the current debate often skips
A common defense — that the cameras help solve crimes and thus are justified — skips a more fundamental question: what kind of crime‑fighting system has Flock designed through decisions about what to collect, who can search, how long to retain data, and how broadly to share it?
For example, requiring a case number is meant to signal legitimacy, but without automatic verification against police records it is a weak guardrail. A stronger design would require that case numbers match the issuing department’s records, creating a more intrusive integration but a more reliable audit trail.
Flock most commonly points to kidnapping and missing‑person cases as a key use case. A nationwide camera network could be valuable in such emergencies. But it is possible to design access controls that restrict broader searches to those tied to active Amber Alerts or similar emergency declarations, thereby preserving the network’s emergency utility without normalizing wide‑ranging data access.
There is also the question of data volume and retention: Flock primarily operates as a national network—police in one city can query data collected in another, and agencies can retain captures for months or years. Flock states that 90% of searches occur within a week of an incident, which suggests an alternative bargain: limit sharing and retention to what is demonstrably useful for solving crimes. The company has recently recommended a seven‑day retention period, but in practice agencies can keep data as long as they choose.
Business model, politics, and possible futures
Narrowing the system’s scope would undercut Flock’s pitch to police departments. ALPRs have existed since the 1990s for tolling and ticketing, but Flock’s business model—and a recent valuation of about $8 billion—depends on converting cameras into a large, data‑rich network that lets departments analyze not only their own data but others’ as well.
Civil‑liberty groups remain skeptical. Chad Marlow, senior policy counsel at the American Civil Liberties Union (ACLU), half‑joked that the only acceptable Flock contract to him would be “one that is never signed,” and argued that limits on surveillance are best set by law rather than corporate guidelines. Flock CEO Garrett Langley acknowledged that he will “probably always have a different view than the ACLU.”
Some municipalities have already canceled contracts, some have moved to competitors, and others are pausing to allow residents to deliberate and craft local rules for police use of the technology. The emerging picture is one in which communities may increasingly define their own bargains over how much surveillance they will accept in exchange for the crime‑fighting benefits these systems claim to provide.
