On Wednesday, work to remove a set of AI-powered, license plate reading Flock cameras from the City of Verona is expected to begin. Until then, local officials have chosen to physically cover the cameras, blocking their ability to monitor passing traffic. 

A lack of public trust not in the police department, but in the company Flock Safety, fueled the decision. Despite the Verona Common Council vote last fall not to renew the city’s contract with Flock, and the contract lapsing in December, the cameras have remained in place. 

Mayor Luke Diaz said the police department had made several requests to Flock for the cameras to be removed. “They weren’t removing them,” Diaz told the Wisconsin Examiner. “We kind of looked at the contract, talked it over amongst staff, and the thing we felt most comfortable with was just covering them so they could stop spying on people.”

“I’m 100% certain that they were still working,” Diaz said, adding that some other communities have had similar experiences with Flock refusing to remove unwanted cameras. “It could have been an accident, it could have been an oversight on their part, but I think it was deliberate,” Diaz told the Examiner.“Because I think that they want to keep the cameras up, whether they have permission or not.” 

Concerns about Flock cameras, which are equipped with AI-powered automatic license plate reader technology, are on the rise nationwide. The cameras take pictures of passing vehicles, storing them for up to 30 days in a database which organizes the images based on identifiable license plates and vehicle descriptions. Law enforcement agencies are able to search Flock’s network of images, including those captured in other parts of the country. 

Any Flock network could contain thousands or even millions of compiled law enforcement searches. Exactly why those searches are being done, however, isn’t always clear. An analysis of Flock audit data by the Wisconsin Examiner found that from January to May of 2025, Flock’s network was searched by 221 unique local and state law enforcement agencies. The most common search term turned out to be “investigation” without other context to determine the reason for  the search.

Some agencies used even vaguer terms such as “cooch,” “hunt,” or just “.”  After the Examiner’s first report on Flock, a Waukesha police officer who repeatedly used only a period to label Flock searches underwent re-training on proper use of the system. By contrast the West Allis Police Department, which used “.” to search Flock more than any other Wisconsin law enforcement agency from January to May 2025, admitted no wrongdoing and asserted that its officers are properly trained on the Flock system. Recently, 404 Media reported that law enforcement officers in some parts of the country have been advised to be as “vague as permissible” when entering reasons for using Flock’s network.

Other cases have also emerged involving officers outright misusing the Flock system. A Menasha police officer is currently facing charges of felony misconduct in public office for using Flock’s network to track a vehicle belonging to a private person while off duty. In Kenosha County, a sheriff’s deputy was accused of using Flock and a squad car tracking system called Polaris to stalk one of his co-workers. Similar cases of officers using Flock to stalk love interests or others have also surfaced, as well as at least one use of Flock by a Texas sheriff’s office in an abortion-related case. 

There are also fears about how the cameras can be used by the federal government to monitor local communities, especially for immigration enforcement. Those sorts of questions led Verona city officials to take a closer look at what their own police department’s Flock data revealed. In Minneapolis, immigration and border patrol agents have been involved in numerous clashes with local residents, raising concerns about monitoring of protesters and legal observers.

Just before Verona voted not to renew its contract with Flock, Verona Police Chief Dave Dresser tried to ease some of the public’s concerns. “The data’s only stored for 30 days, which is actually very restrictive,” said Dresser. “After 30 days, the data is purged. I believe there is misinformation that the data’s held for months and months or years, it’s not. It’s purged.” Dresser added, “we’ve opted out of sharing data with federal agencies, we understand the concerns there. We have revoked automatic access to our data from out of state agencies to address some of the privacy concerns.”

In a document outlining her own review of Verona’s Flock data, Ald. Beth Tucker Long stressed that “I am not against participation in the Flock network because I think our officers are doing anything inappropriate.” In fact, Tucker Long wrote, “I am very proud of our police force and I know that our officers conduct themselves with honor and integrity.” Tucker Long said that “Flock is not operating with integrity,” and focused on the federal government’s level of access. 

Within Verona’s Flock network there were 974 searches tagged as “federal” in October 2025, Tucker Long said, despite federal access to Flock having allegedly been cut off months before. Another 1,628 searches were done by organizations “self-identifying as ICE,” according to Tucker Long. “This does not include organizations that did not disclose that the searches were for ICE.” Over 5,700 Flock searches were done for “other image search,” which means that law enforcement did not search for a license plate, but rather used AI to search the full contents of an image. Tucker Long also pointed to nearly 1,100 searches which were logged as “Outside Assist,” implying that information was shared with another organization whose identity was not recorded in the system. 

When Flock first came to Verona, Diaz explained, there wasn’t much debate. Although Diaz couldn’t remember everything, he believes it was handled administratively as the sort of equipment request from the police department which wouldn’t necessarily come before the common council for approval. “I don’t think there was the awareness of the abuses the company Flock has made, and I think there’s a lot of stuff happening at the national level where it’s clear and obvious that we have a federal government that doesn’t believe in the Fourth Amendment, or the First Amendment, or the Fourteenth, and the Fifth. And that this Supreme Court isn’t going to stand up for the Constitution either, and so I think that’s created a lot of angst and awareness. And that people are looking around at these Flock things and saying these aren’t benign. They aren’t just like a helpful tool for the local police department. They’re a way for the feds to spy on our communities.” 

A Verona police spokesperson told the Examiner that the department is “committed to exploring other alternative tools and strategies” which will maintain the high standards city residents have come to expect. The spokesperson added that the department was encouraged that the decision to remove Flock was due to a lack of confidence in the multi-billion dollar company, and not the police department.

As part of its deportation efforts, the Trump administration has ordered states to hand over personal data from voter rolls, driver’s license records and programs such as Medicaid and food stamps.

At the same time, the administration is trying to consolidate the bits of personal data held across federal agencies, creating a single trove of information on people who live in the United States.

Many left-leaning states and cities are trying to protect their residents’ personal information amid the immigration crackdown. But a growing number of conservative lawmakers also want to curb the use of surveillance technologies, such as automated license plate readers, that can be used to identify and track people.

Conservative-led states such as Arkansas, Idaho and Montana enacted laws last year designed to protect the personal data collected through license plate readers and other means. They joined at least five left-leaning states — Illinois, Massachusetts, Minnesota, New York and Washington — that specifically blocked U.S. Immigration and Customs Enforcement from accessing their driver’s license records.

In addition, Democratic-led cities in Colorado, Illinois, Massachusetts, New York, North Carolina, Texas and Washington last year terminated their contracts with Flock Safety, the largest provider of license plate readers in the U.S.

The Trump administration’s goal is to create a “surveillance dragnet across the country,” said William Owen, communications director at the Surveillance Technology Oversight Project, a nonprofit that advocates for stronger privacy laws.

“We’re entering an increasingly dystopian era of high-tech surveillance,” Owen said. Intelligence sharing between various levels of government, he said, has “allowed ICE to sidestep sanctuary laws and co-opt local police databases and surveillance tools, including license plate readers, facial recognition and other technologies.”

A new Montana law bars government entities from accessing electronic communications and related material without a warrant. Republican state Sen. Daniel Emrich, the law’s author, said “the most important thing that our entire justice system is based on is the principle against unlawful search and seizure” — the right enshrined in the Fourth Amendment to the U.S. Constitution.

“It’s tough to find individuals who are constitutionally grounded and understand the necessity of keeping the Fourth Amendment rights intact at all times for all reasons — with minimal or zero exceptions,” Emrich said in an interview.

ICE did not respond to Stateline’s requests for comment.

Automated license plate readers

Recently, cities and states have grown particularly concerned over the use of automated license plate readers (ALPRs), which are high-speed camera and computer systems that capture license plate information on vehicles that drive by. These readers sit on top of police cars and streetlights or can be hidden within construction barrels and utility poles.

Some cameras collect data that gets stored in databases for years, raising concerns among privacy advocates. One report from the Brennan Center for Justice, a progressive think tank at New York University, found the data can be susceptible to hacking. Different agencies have varying policies on how long they keep the data, according to the International Association of Chiefs of Police, a law enforcement advocacy group.

Supporters of the technology, including many in law enforcement, say the technology is a powerful tool for tracking down criminal suspects.

Flock Safety says it has cameras in more than 5,000 communities and is connected to more than 4,800 law enforcement agencies across 49 states. The company claims its cameras conduct more than 20 billion license plate reads a month. It collects the data and gives it to police departments, which use the information to locate people.

Holly Beilin, a spokesperson for Flock Safety, told Stateline that while there are local police agencies that may be working with ICE, the company does not have a contractual relationship with the agency. Beilin also said that many liberal and even sanctuary cities continue to sign contracts with Flock Safety. She noted that the cameras have been used to solve some high-profile crimes, including identifying and leading police to the man who committed the Brown University shooting and killed an MIT professor at the end of last year.

“Agencies and cities are very much able to use this technology in a way that complies with their values. So they do not have to share data out of state,” Beilin said.

Pushback over data’s use

But critics, such as the American Civil Liberties Union, say that Flock Safety’s cameras are not only “giving even the smallest-town police chief access to an enormously powerful driver-surveillance tool,” but also that the data is being used by ICE. One news outlet, 404 Media, obtained records of these searches and found many were being carried out by local officers on behalf of ICE.

Last spring, the Denver City Council unanimously voted to terminate its contract with Flock Safety, but Democratic Mayor Mike Johnston unilaterally extended the contract in October, arguing that the technology was a useful crime-fighting tool.

The ACLU of Colorado has vehemently opposed the cameras, saying last August that audit logs from the Denver Police Department show more than 1,400 searches had been conducted for ICE since June 2024.

“The conversation has really gotten bigger because of the federal landscape and the focus, not only on immigrants and the functionality of ICE right now, but also on the side of really trying to reduce and or eliminate protections in regards to access to reproductive care and gender affirming care,” Anaya Robinson, public policy director at the ACLU of Colorado.

“When we erode rights and access for a particular community, it’s just a matter of time before that erosion starts to touch other communities.”

Jimmy Monto, a Democratic city councilor in Syracuse, New York, led the charge to eliminate Flock Safety’s contract in his city.

“Syracuse has a very large immigrant population, a very large new American population, refugees that have resettled and been resettled here. So it’s a very sensitive issue,” Monto said, adding that license plate readers allow anyone reviewing the data to determine someone’s immigration status without a warrant.

“When we sign a contract with someone who is collecting data on the citizens who live in a city, we have to be hyper-focused on exactly what they are doing while we’re also giving police departments the tools that they need to also solve homicides, right?” Monto said.

“Certainly, if license plate readers are helpful in that way, I think the scope is right. But we have to make sure that that’s what we’re using it for, and that the companies that we are contracting with are acting in good faith.”

Emrich, the Montana lawmaker, said everyone should be concerned about protecting constitutional privacy rights, regardless of their political views.

“If the government is obtaining data in violation of constitutional rights, they could be violating a whole slew of individuals’ constitutional rights in pursuit of the individuals who may or may not be protected under those same constitutional rights,” he said.
