Flock Wants to Track Every Driver in America—and Apparently We’re Supposed to Be Grateful

A Wrongful Police Stop Is Not a Minor Software Bug

The renewed scrutiny began after automotive journalist Joel Feder was wrongfully tracked and stopped by police .

An officer had entered an incomplete license plate into the FBI’s National Crime Information Center. Flock’s system identified Feder’s press vehicle as a possible match, and local officers failed to properly verify the complete plate before surrounding Feder and his wife in a parking lot.

Flock did not originate every error in that chain. That distinction matters. Bad information came from law enforcement, and officers failed to perform the necessary final verification.

But Flock’s technology took that bad information, searched an automated surveillance network and delivered the supposedly relevant vehicle to police.

That is what automation does: It makes everything faster—including mistakes.

A typo in a filing cabinet affects whoever eventually opens the drawer. A typo connected to a nationwide camera network can follow an innocent driver across multiple jurisdictions and place that person in a potentially dangerous encounter with armed police.

Feder was even warned that correcting the problem with one police department would not necessarily prevent another department from stopping him again. Flock’s local suppression option does not automatically correct the underlying NCIC record or protect the driver everywhere else.

Langley said he wants the likelihood of a wrongful stop to reach zero. That is a lovely goal. He also acknowledged that Feder was not the first person caught in this kind of failure.

He certainly was not.

The Institute for Justice has documented at least 27 known incidents involving ALPR errors or bad data that resulted in innocent motorists being stopped, detained, held at gunpoint or jailed. The organization warns that the true number is probably higher because no comprehensive national database tracks these incidents.

In one Arkansas case, a Flock camera reportedly misread a plate, resulting in police detaining an innocent couple at gunpoint while their six-week-old child remained inside the vehicle. In Florida, a driver was jailed for 13 days after officers incorrectly associated his vehicle with a fatal crash.

Those are not harmless “edge cases” to the people staring down police weapons or sitting in jail cells.

The Constitution Is Not “Cut and Dry”

During the interview, Langley also dismissed the constitutional issue as essentially settled.

According to The Drive’s report on his comments , Langley argued that courts have determined Flock’s technology does not constitute a warrantless search under the Fourth Amendment.

That is an extremely convenient summary for the CEO of the company selling the cameras.

A federal district court did rule in January 2026 that Norfolk, Virginia’s network of 176 Flock cameras did not constitute a Fourth Amendment search under the specific facts presented in that case. The court found that the available data points were too scattered to reveal the comprehensive movements of a person in the same way as continuous GPS or cellphone-location tracking. Read the court decision .

But the case is currently on appeal.

The ACLU, ACLU of Virginia and Electronic Frontier Foundation filed a brief with the Fourth Circuit in April 2026 arguing that these interconnected databases allow law enforcement agencies to retrospectively examine sensitive information about drivers’ movements without a warrant.

Even the district court acknowledged that the constitutional calculation could change as the number and capabilities of ALPR cameras expand.

In other words, the exact nationwide expansion Langley is proposing could make the constitutional problem substantially worse.

Calling the issue “cut and dry” while an active federal appeal challenges the technology is not reassuring. It is corporate messaging designed to make an unresolved civil-liberties debate sound finished.

Thirty Days of Surveillance Is Still Surveillance

Flock emphasizes that its default retention period is 30 days and that customer agencies generally control access and sharing.

According to Flock’s own data policy , its cameras can collect license plate images, vehicle characteristics, timestamps and camera locations. Searches are logged, and data is normally deleted automatically after the retention period.

Flock also says it does not use the system for mass surveillance or tracking individuals.

Here is the problem: A system can indiscriminately record every passing vehicle, store its identifying characteristics and location, permit retrospective searches, connect multiple jurisdictions—and still insist that it is not conducting mass surveillance because only authorized users can search the results.

That is a definition written by the company benefiting from the distinction.

Thirty days is not a trivial amount of time. Thirty days can reveal where someone works, where their children attend school, which medical offices they visit, where they worship, which political events they attend and whose homes they regularly visit.

Flock’s evidence policy also allows retention periods of up to one year when approved by an elected official or governing body.

The question is not simply whether the company eventually deletes the data.

The question is why the government should be allowed to build a searchable history of innocent people’s movements in the first place without obtaining a warrant.

Search Logs Do Not Prevent Abuse

Flock repeatedly points to access controls, required search reasons and audit logs as safeguards.

Those measures are better than unrestricted anonymous access. They are not the same thing as preventing abuse.

The Institute for Justice has identified at least 28 reported cases in which officers allegedly used ALPR systems to follow romantic partners, former partners, coworkers or other personal targets.

According to the organization’s review, only a small number of those cases were initially uncovered through internal investigations. Most became known after victims reported suspicious behavior or broader allegations of stalking.

That exposes the enormous hole in the “every search is logged” defense.

A log proves that somebody accessed the system. It does not guarantee that anyone is reviewing the access in real time. It does not prevent the search from occurring. It does not tell the targeted person that an officer looked them up.

It simply leaves evidence after the privacy violation has already happened.

That is not a preventative safeguard. It is a receipt.

Mission Creep Has Already Arrived

Flock cameras are marketed using serious crimes: stolen cars, kidnappings, shootings and missing persons.

Once a surveillance system exists, however, its use rarely remains confined to the most extreme cases used to sell it.

The Electronic Frontier Foundation analyzed millions of Flock searches and found the technology being used for matters including school-residency verification, employment background investigations and noise complaints.

EFF has also documented searches associated with political protests, activists, reproductive-health investigations and immigration enforcement .

Meanwhile, the U.S. Government Accountability Office found that several Department of Homeland Security agencies had access to nationwide third-party license plate databases. The GAO concluded that agency policies did not always address important privacy protections and issued recommendations concerning privacy and bias risks.

This is how surveillance expands.

First, we are told the cameras are for stolen cars.

Then they are used for loud music.

Then residency checks.

Then protests.

Then immigration enforcement.

Then an officer’s ex-girlfriend.

The infrastructure remains the same. Only the excuse for searching it changes.

Public-Safety Claims Require Independent Proof

Langley told The Drive that Flock helped solve more than one million crimes during the previous year. He also claimed that reducing retention from 30 days to 14 days would result in approximately 30% fewer crimes being solved.

The Drive specifically noted that it was not provided independent verification or sourcing for those figures. Read the full report .

That does not automatically make the claims false. It does mean taxpayers, city councils and police departments should not accept them as proven simply because the vendor presented them.

What does “helped solve” mean? Did a Flock alert directly identify a suspect? Did it provide one minor data point? Was it searched during an investigation without affecting the result? How many successful alerts involved serious crimes, and how many involved low-level matters?

How many false alerts occurred? How many innocent people were stopped? How many searches violated agency policy? How often were audits performed? How many violations were discovered internally rather than through a victim’s complaint?

A private surveillance company should not get to grade its own homework while selling subscription contracts to governments using public money.

Safety Does Not Require Blind Trust

This does not have to be a choice between banning every camera and accepting a private nationwide tracking network.

At a minimum, communities considering this technology should require:

• A warrant for searches of historical movement data, except during clearly defined emergencies.
• Independent accuracy testing using real-world conditions.
• Public reporting of false alerts, wrongful stops and misuse.
• Automatic alerts when officers conduct suspicious or repeated searches.
• Strict limits on cross-jurisdictional and federal data sharing.
• Short retention periods that cannot be quietly extended.
• Meaningful penalties for unauthorized searches.
• Public approval before deployment, expansion or contract renewal.
• Independent evidence supporting crime-reduction claims.
• A clear process for innocent drivers to correct bad records before another department stops them.

These are not unreasonable obstacles to public safety. They are the kind of basic safeguards that should exist before a government contractor starts documenting the movements of an entire population.

We Are Not Customers. We Are the Product Being Watched.

Flock’s CEO describes expansion into every American city as an exciting future.

For the rest of us, it looks more like a country where every ordinary trip creates another government-accessible data point.

Drive to work: recorded.

Visit a friend: recorded.

Attend a protest: recorded.

See a doctor: recorded.

Pass through the wrong intersection while an officer has entered the wrong plate: potentially surrounded by police.

Flock can argue that government agencies technically own the data. It can promise that searches are logged. It can point to a 30-day default retention period. It can insist that tracking everyone’s vehicles is somehow not mass surveillance.

None of that changes the central fact:

Millions of Americans who are suspected of absolutely nothing are having their movements collected so that the government might decide to search them later.

And now the company responsible wants to put that system in every city in America.

No, thanks.

Public safety matters. So do constitutional rights, privacy, due process and the basic expectation that leaving your driveway does not enroll you in a privately operated police-tracking network.

Flock may want a camera in every city.

The rest of us should be asking who authorized that future—and why we were never asked.
