A surveillance startup has quietly blanketed the country with more than 100,000 license plate reader cameras, and a fast-growing grassroots movement of privacy-minded Americans is pushing back hard, through city halls and, in some cases, with bolt cutters.
Flock Safety, the company behind the cameras, sells its technology to police departments, homeowners' associations, and businesses as a crime-fighting tool. The devices snap still images of passing vehicles, capturing make, model, color, license plate, and distinguishing features. That data sits in a cloud database for up to one month and can be shared across state lines with other Flock subscribers. Law enforcement agencies query the system on practically any case that involves a car.
But the sheer scale of the network, and a string of documented abuses, has triggered a revolt that now stretches from small Virginia towns to Los Angeles. The ACLU tallied more than 70 municipalities that have ended their Flock contracts in recent months. A Facebook group called DeFlock America has swelled past 600,000 members and keeps adding thousands every day. And a 20-year-old Minneapolis-area man who goes by "Nomark" has become the movement's most visible figure, claiming to have personally disabled roughly 30 cameras near his home.
Nomark dresses in all black when he goes out at night to disable Flock cameras. He posts how-to guides for his roughly 500,000 Instagram followers, walking them through methods for rendering the devices useless. He told AFP he was "super nervous" the first time he vandalized a camera but added, "I'm not really as scared anymore."
Like-minded individuals across the country have followed his lead in recent weeks. The vandalism is not confined to one city or region. In Houston, four Flock cameras were cut down, two earlier in the week and two more near a city park, and Houston police opened an investigation into the incidents. On Long Island, four cameras in Southold were hit in July 2026. Methods there included paint splattering, wire unplugging, and one camera being run over by a vehicle.
Southold Police Chief Steve Grattan described the damage:
"We had two cameras vandalized on July 4 weekend, both had paint splattered on them and one had the wires unplugged."
Anti-Flock activists have also built crowdsourced online maps marking camera locations and shared blocking techniques through social media channels. The movement has drawn supporters from across the political spectrum. Tucker Carlson called the vandals "decent, patriotic Americans" who are simply "taking matters into their own hands." The ACLU's senior policy counsel, Chad Marlow, said the grassroots opposition has been "stunning" in its growth.
"There is really an incredible grassroots movement against Flock."
That was Marlow's assessment, and the numbers back him up.
Privacy concerns alone might not have produced this level of public anger. What lit the fuse was a pattern of law enforcement misuse that confirmed opponents' worst fears about warrantless vehicle tracking.
A Washington Post investigation found at least 50 police officers accused of misusing the Flock system. In Georgia, the problem was stark: 18 police officers, including a supervisor who used Flock cameras to track her boyfriend, were arrested for misusing the data, the New York Post reported. U.S. media reports also described cases in which officers allegedly sent Flock data to immigration agents and used the system to track women who had obtained abortions, conduct described as illegal in several states.
The errors cut the other direction, too. The Institute for Justice, a libertarian law firm, has documented dozens of cases in which innocent people were pulled over, detained, or even arrested because of license plate reader mistakes. A wrong digit, a misread plate, a stolen-car flag that was never cleared, and an ordinary driver ends up in handcuffs on the side of the road.
Flock Safety CEO Garrett Langley has not helped his company's public standing. He accused some opponents of being "terrorists", a label that landed poorly with Americans who see themselves as exercising basic civic resistance against unchecked surveillance.
Law enforcement officials argue the cameras are indispensable. In Richmond, Virginia's capital, the police department has used Flock since 2023. Jon Bridges, a Richmond police official, described how the system aided a domestic-related double homicide investigation in May. Detectives queried the Flock database, identified the suspect's vehicle by its license plate, and tracked it to a neighboring county, where the suspect was arrested.
Bridges made no apology for the department's reliance on the technology:
"Practically any crime that has a connection with a vehicle or a vehicle involved, we will at least query the database to see if there's anything there."
That statement captures both the appeal and the problem. When police query the database on "practically any crime," the system functions less like a targeted investigative tool and more like a dragnet, logging the movements of every car that passes a camera, guilty or not, and storing that data where any subscribing agency can search it.
Flock Safety has expanded to more than 5,000 police agencies nationwide with nearly 90,000 cameras since its founding in 2018, according to DeFlock activists. The company's own figure, more than 100,000 cameras, is even higher. Either number represents a surveillance footprint that did not exist a decade ago and that was built largely without public debate.
Steven Keener, a criminology professor at Christopher Newport University in Virginia, pointed out that the fight against Flock is winnable precisely because the contracts are local. Residents do not need to lobby Congress or wait for a federal agency to act. They can walk into a city council meeting.
"Because decisions are at the local level, people realize that they can actually make a difference."
Keener encouraged residents to "meet with city council members or mayors to convince them to cancel their contracts with the surveillance company." That approach has already produced results. The ACLU's count of more than 70 municipal cancellations spans cities as large as Los Angeles and towns small enough that a few dozen residents showing up at a public hearing can shift a vote.
Legislative efforts are also underway at both the state and federal levels to regulate or defund license plate reader programs, though no specific bills were identified in the available reporting.
The tension at the heart of this fight is straightforward. Police want a tool that helps them catch killers. Citizens want to drive to work without their movements being logged in a searchable database accessible to thousands of agencies, and potentially abused by rogue officers tracking ex-girlfriends, political opponents, or women seeking legal medical care.
Both sides have a point. But when 50 officers have already been accused of misusing the system, when 18 have been arrested in a single state, and when the company's own CEO responds to critics by calling them terrorists, the burden of proof shifts. The people asking hard questions about Flock are not the ones who need to justify themselves. The company and its government clients are.
Americans have always understood that safety and liberty require trade-offs, but they have never agreed to let a startup and a few thousand police departments make that trade-off for them, in the dark, one camera at a time.
