A Connecticut law that took effect at the beginning of October imposes new restrictions on police use of automated license plate readers (ALPRs), which enable what a federal judge recently described as "a type of indiscriminate mass surveillance." The law reflects the bipartisan backlash against AI-assisted cameras that record images of passing cars billions of times a week, building databases that police can use to track drivers, identify other vehicles in their vicinity, predict itineraries, and conduct searches based on a wide range of vehicle characteristics.

Connecticut previously imposed no statutory limits on ALPRs, a fact that underlines how readily police can access license plate data, which they can search without any sort of judicial review and often without meaningful internal supervision. But the law's provisions, while promising in some ways, fall short of the reforms recommended by critics who warn that unconstrained use of ALPRs threatens the privacy of innocent motorists across the country.

As of today, DeFlock's mapping project has identified nearly 145,000 ALPR cameras in the United States, most of which were installed by Flock Safety, the leading vendor. That network includes more than 1,500 cameras deployed by Connecticut law enforcement agencies, three-quarters of which use the technology.

The concerns underlying the new law, which Gov. Ned Lamont signed last May, echo objections raised in other states. Last February, for example, CT Insider reported that out-of-state agencies had searched ALPR data from Connecticut thousands of times for immigration enforcement purposes. When police in Johnson City, Texas, searched Connecticut data for a missing woman, the log noted that she "had an abortion," which reinforced concerns that ALPR information might be used to enforce abortion bans.

As elsewhere, ALPR critics in Connecticut also have complained about a lack of transparency. In April 2025, for instance, South Windsor began using Flock cameras without any public notice. The resulting consternation prompted the city council to cancel the program early this month. CT Mirror reports that South Windsor is "at least the sixth Connecticut community to end or suspend the use of ALPRs this year, following Windsor, Killingworth, Ledyard, Milford and Newtown."

Compared to those moves, the new state restrictions are pretty weak tea. But they include some potentially meaningful changes, and they highlight how lax oversight of ALPRs has been.

The new law restricts the sharing of ALPR data, which henceforth will be limited to Connecticut, Massachusetts, New York, and Rhode Island unless an agency in another state obtains a judicial warrant. The law says the data may not be used for immigration enforcement, to target conduct protected by the First Amendment, or for investigations related to "reproductive" or "gender-affirming" health care services. It also bars the placement of ALPRs near facilities that provide such services or organizations that primarily serve immigrants.

The original bill specified that ALPR data could be retained for no more than seven days unless it is tied to an ongoing criminal investigation, subject to a warrant, or used for toll enforcement. The final version of the bill extended that limit to 21 days. Flock's original default was 30 days. But last August, in response to widespread criticism of ALPR surveillance, the company began recommending a seven-day limit. Connecticut's Police Officer Standards and Training Council, which last month sent Lamont a report that included suggested reforms, thinks the state should adopt the seven-day standard.

Under the new law, police may search ALPR data to "assist in the recovery of a stolen motor vehicle," "assist in locating a missing or endangered individual," or "assist in the apprehension of an individual with an outstanding warrant." They also may query the database for information "relevant and material to a specific active investigation of a criminal offense in which there is reasonable suspicion that the offense has been or is being committed." When they do that, their agency must record "the reason for the access and any associated case number for the complaint or incident that is being investigated and is the basis for the access."

It is remarkable that Connecticut lacked such basic safeguards until now, and it is not clear how effective the new rules will be. Since July 1, 2025, Virginia has required that cops state a "specific purpose" for ALPR searches, including "the offense type." Yet last April, WHRO reported that Norfolk police often give "incomplete and imprecise reasons" for ALPR queries, including "suspect," "suspicious," and "investigation" or "inv."

Connecticut's "reasonable suspicion" requirement is more lenient than the standard that the Institute for Justice favors. The organization's model statute would generally require a warrant based on probable cause for ALPR queries. The proposed law makes exceptions for "exigent circumstances," stolen vehicles, and toll, parking, or traffic enforcement.

Connecticut's law also addresses the sort of blatant abuses that have fueled opposition to license plate cameras, including cases in which cops have been caught using ALPR data to stalk personal nemeses, ex-girlfriends, possibly unfaithful spouses, and objects of romantic interest. The law says an officer "who is found to have knowingly accessed, used or disseminated automated license plate reader data with malicious intent for purposes outside of the provisions of this section shall be subject to disciplinary action including, but not limited to, suspension, cancellation or revocation of certification" for police work.

The law establishes two additional remedies that could deter ALPR abuses. It authorizes the attorney general to sue ALPR contractors for damages and injunctive relief when they violate the new restrictions. It also allows "any aggrieved individual" to sue "a public agency" that flouts the rules.

"The law, for a first bite at the apple, is not bad," Ken Barone, manager of the University of Connecticut's Racial Profiling Prohibition Project, told CT Insider. Given that "there was a benchmark of nothing," he said, the attempt to constrain and track ALPR use is "a big step forward."

West Des Moines, Iowa—Iowa voters may disagree on immigration, taxes, and the economy, but government surveillance is drawing opposition from across the political spectrum.

An Emerson College poll of 750 likely Iowa voters, conducted between late August and early September, found that 61 percent opposed police use of automated license plate reader (ALPR) cameras, compared with 26 percent in support.

The backlash comes as police departments across the state increasingly rely on surveillance technology supplied by private companies such as Flock Safety and Motorola Solutions. Their cameras record license plates and vehicle information, feeding searchable databases that allow law enforcement to piece together motorists' movements, including those of people suspected of no crime.

As Iowa's gubernatorial and congressional campaigns enter their final stretch, voters are increasingly pressing candidates on whether they intend to place limits on the technology. Jacqueline Thompson, an ordained elder in the Iowa Conference of the United Methodist Church and a self-described centrist Democrat, said she has been concerned about government surveillance for years.

"It's always been important to me [and] I've always thought that was a problem," she said before a campaign rally at a senior living community in Des Moines earlier this month. "So, when people started jumping on the bandwagon saying it, I was like, 'Hello, I've been here already!'"

Thompson pointed to two Democratic candidates, Nate Willems, who is running for Iowa attorney general, and Taylor Wettach, a candidate for state auditor, as having caught her attention with their emphasis on corporate oversight and access to government records.

For Thompson, the renewed attention to privacy is a welcome development in a political environment where Democrats and Republicans rarely find common ground. "It's kind of nice to hear the people come back to the middle [and discuss this]," she said.

Flock Does Not Have Enough Guardrails

Police surveillance technology has spread across Iowa faster than the rules governing its use.

A recent study identified at least 62 Iowa law enforcement agencies that had accessed other agencies' Flock databases, including departments that did not operate cameras of their own. Police departments can therefore search information collected well beyond their jurisdictions without having to install a single camera themselves. The study (led by Megan Graham, a clinical associate professor and director of the Technology Law Clinic at the University of Iowa College of Law) found significant gaps in transparency surrounding ALPRs.

The constitutional implications are already being tested in court. On October 1, a federal judge in Oklahoma ruled that a sheriff's deputy violated the Fourth Amendment by searching a motorist's location history through automated license plate reader systems operated by Flock Safety and Motorola Solutions without a warrant.

The search turned up more than 50 records of the driver's whereabouts across multiple states over a month. In the 38-page ruling, the judge ordered the resulting evidence suppressed, describing the technology as a form of "indiscriminate mass surveillance." The decision is not binding in Iowa, and legal challenges to ALPR surveillance still face an uphill battle, but it adds to the legal scrutiny of police tracking motorists without warrants.

The University of Iowa study also raised concerns about unauthorized database access, erroneous alerts, and the potential use of locally collected information for federal immigration enforcement.

Flock Safety says it has not provided U.S. Immigration and Customs Enforcement or Border Patrol with direct access to its systems. But the researchers found that local law enforcement agencies elsewhere in the country had conducted searches on behalf of federal authorities, effectively allowing them to obtain information without direct access.

Taxpayers are also footing the bill. Cedar Rapids reported operating 76 cameras at a combined average cost of more than $20,000 a month, according to the study.

Researchers struggled to determine the full extent of surveillance across Iowa. Some agencies refused to disclose the number or locations of their cameras, while others withheld records concerning unauthorized access or erroneous alerts, citing confidentiality.

The cameras are not limited to Iowa's largest cities. Becca Eastwood, deputy policy director at the American Civil Liberties Union of Iowa, said they have spread across large, midsize, and smaller communities, prompting a surge in opposition over the past year.

The backlash "has just exploded, like no other issue that I have seen in my time at the ACLU," Eastwood told Reason in an interview. Candidates running for state and federal offices are increasingly getting asked if they support police departments using ALPR cameras, she said. 

Some local governments are already reconsidering their contracts. Indianola and Waukee suspended their Flock camera arrangements, Iowa Public Radio reported in August. Dallas County paused a planned rollout while awaiting guidance from state lawmakers. Ankeny, which operates 16 Flock cameras, is reportedly expected to reconsider a possible contract extension next year.

The backlash also cuts across the immigration debate. While concerns about federal immigration enforcement have helped draw attention to the cameras, critics argue the same surveillance infrastructure can be used against anyone, regardless of which party controls the government.

"This is a nonpartisan issue because people recognize that surveillance can be weaponized against anyone the government wants to weaponize it against," Eastwood said. "An increase in police surveillance impacts certain populations more, right now [but] nobody is immune."

Politicians Face Pressure To Cut Ties With Flock

The opposition is beginning to force Iowa's candidates to take positions on a technology that, until recently, attracted relatively little attention outside law enforcement and civil liberties circles.

Among the gubernatorial candidates, interviewed by Iowa Radio last month, Republican Zach Lahn has called for state-level regulation, arguing that the widespread collection of information about where people drive is unacceptable. Meanwhile, Democrat Rob Sand has expressed support for safeguards governing the collection and use of license plate data and said he would sign legislation if privacy concerns persisted. But he has also pointed to the cancellation of some Flock contracts as evidence that the market is responding to public concerns. 

For now, neither approach offers much clarity on whether police should be required to obtain warrants before searching motorists' location histories or how far restrictions on data collection should go.

Ryan Johnson, a libertarian-leaning Republican who works as a machinist near Waterloo, said he could accept cameras in certain locations, such as downtown areas or near traffic signals. But he objects to their spread into residential neighborhoods and public spaces.

"Just having Flock cameras everywhere, [in] residential [areas], putting them at parks and pools, we don't need that," Johnson said while attending a Lahn rally earlier this month.

So far, some of the most concrete changes to ALPR practices have come from Flock itself. In August, the company announced that it would reduce its default data-retention period from 30 days to seven and require officers to enter a criminal case number or code for each search. The changes would not, however, require police to obtain a warrant before accessing the records.

Gary and Nancy Guthrie, a Democratic couple attending a Des Moines rally supporting Chris Jones for secretary of agriculture, remain skeptical of the cameras.

"I don't have a good feel for that," Nancy Guthrie said. "Personally, I'm very much against Flock cameras."

For all the attention the issue is receiving on the campaign trail, Iowa voters have yet to hear much about what legal limits candidates would actually impose on police surveillance.
