Flock Cameras: Public Safety Needs Tools, Liberty Needs Guardrails
A camera mounted above a Santa Rosa intersection may not look like much.
Cars pass beneath it. A parent drives a child to school. A caregiver heads to a medical appointment. A worker drives home after a late shift. A stolen car may pass through. So may a suspect vehicle linked to a shooting, robbery, kidnapping, or missing-person case.
That is both the promise and the problem with automated license plate readers.
The same technology can help police find someone who needs to be found. It can also record the movements of people who have done nothing wrong.
That is why the debate over Flock cameras should not be reduced to a simple yes-or-no question. Santa Rosa and other communities should be willing to use effective public safety tools, but only if accompanied by strong policies, public transparency, regular audits, and clear limits on data sharing.
Public safety matters.
So do people’s liberties.
One should never be used as an excuse to weaken the other.
A useful tool
Flock cameras are automated license plate readers. They capture license plate numbers and other vehicle information, then allow law enforcement agencies to compare that information against lists of stolen vehicles, wanted vehicles, missing persons, or vehicles connected to criminal investigations.
The Press Democrat reported that Flock cameras are used by more than 5,000 police agencies, including 350 in California, and by thousands of neighborhood groups and businesses across 49 states. Santa Rosa has the largest Flock network in the North Bay, with 129 license plate readers and surveillance cameras, and four more awaiting installation. The department retains its data for 30 days.
The Press Democrat editorial board later reported that Santa Rosa had 135 Flock Safety cameras that logged about 750,000 vehicles in July. Police searched those records nearly 1,000 times. Windsor, Healdsburg, Rohnert Park and Sonoma also use the cameras.
Those numbers show both the usefulness and the reach of the system.
Santa Rosa Police Chief John Cregan told The Press Democrat that the cameras have helped generate leads in a bank robbery and home invasion, a kidnapping, and three homicides. He also credited the technology with helping address sideshows, property crimes, and retail theft.
The department’s Flock transparency portal also highlights a January case in which officers identified a suspect in multiple armed robberies. The Press Democrat editorial noted that Berkeley police reported that 52 cameras contributed to 58 arrests and 37 recovered vehicles in one year.
Those are not abstract benefits.
For a robbery victim, a missing person’s family, or a neighborhood shaken by violence, a timely lead can matter deeply. It may mean a suspect is identified sooner. It may mean a stolen car is recovered. It may mean detectives can move from guessing to investigating.
That matters because violent crime is difficult to solve.
In 2024, law enforcement agencies nationwide cleared 43.8% of reported violent crimes through arrest or exceptional means, according to the FBI’s annual crime summary. That means more than half of reported violent crimes remained uncleared that year.
California saw encouraging progress in 2025. CalMatters reported that the state’s homicide clearance rate rose from 64% in 2024 to 79% in 2025, and that the homicide rate fell to 3.5 per 100,000 people, the lowest level recorded by the state since 1966.
Those numbers should not be used to claim that any single technology caused the improvement. Crime trends are complex. But they remind us that solving violent crime matters, especially for victims, families, and neighborhoods that live with unanswered grief.
A tool that helps investigators move faster, identify a suspect vehicle, or rule out a false lead can be valuable.
Technology is not new to policing
Law enforcement has always adapted to technology.
Fingerprinting transformed investigations. DNA evidence helped identify suspects and exonerate the innocent. Surveillance video from homes and businesses became a routine part of solving crimes. Body-worn cameras became tools for evidence collection and accountability. Lawfully obtained cellphone records can help place suspects or victims in time and space.
License plate readers belong in that same conversation.
In a report sponsored by the National Institute of Justice, the RAND Corp. described license plate readers as a tool that can help agencies identify vehicles near crime scenes, test alibis, and analyze crime patterns. RAND also warned that privacy concerns, data retention, and possible misuse are central obstacles to public acceptance.
That is the right balance.
Technology should help police do their work better. It should not allow the government to quietly build a record of ordinary people’s lives without meaningful limits.
The best public safety tools are not just powerful. They are disciplined.
What the research says
Supporters of Flock cameras often cite real cases in which the technology helped locate stolen cars, find missing people, or identify vehicles linked to serious crimes. Those examples matter.
But the research is more cautious than the marketing.
A 2025 review in the Cambridge Journal of Evidence-Based Policing found that studies of automated license plate readers have shown mixed or limited effects on overall crime-control outcomes. Some studies suggest the technology may improve stolen-vehicle recovery or aid certain investigations, but the evidence does not show that license plate readers, by themselves, consistently reduce crime.
That does not mean the cameras are useless. It means we should be honest about what they are.
They are not a stand-alone community safety strategy. They do not replace violence prevention, neighborhood trust, youth outreach, focused deterrence, victim services, good detective work, or strong partnerships between law enforcement and the community.
They are an investigative tool.
A hammer is useful. It is still not a house.
The privacy question
Some people argue that there is no privacy issue because license plates are visible in public.
That is partly true.
The U.S. Supreme Court has said that a person traveling on public roads generally has no reasonable expectation of privacy in movements from one place to another.
But that older idea becomes more complex in the digital age.
There is a difference between an officer seeing one car pass one intersection and a private company’s system collecting searchable records of hundreds of thousands of vehicle movements across a city.
In Santa Rosa, the scale is no longer theoretical. The Press Democrat editorial reported that local cameras logged about 750,000 vehicles in July alone.
That changes the conversation.
In Carpenter v. United States, the Supreme Court recognized that individuals can have a reasonable expectation of privacy in their physical movements, especially when advanced technology enables the government to collect comprehensive location information.
Flock cameras do not track cellphones. They do not monitor every movement of every person. They record vehicles at designated locations.
Still, the principle matters.
Privacy is not only about whether something can be seen. It is also about whether the government can collect, store, search and share that information at a scale no ordinary person could replicate.
The Press Democrat editorial made the point sharply: If a little tracking helps solve crimes, more tracking might solve more crimes. But public safety cannot be the only value. A society could solve many crimes if everyone were required to wear a GPS wristband linked to a police-searchable database. That would not make us free.
Why people are worried
The concerns about Flock are not theoretical.
In 2025, CalMatters reported that Southern California law enforcement agencies violated state law more than 100 times in a single month by sharing automated license plate reader data with federal agents, including Immigration and Customs Enforcement and Customs and Border Protection. California law prohibits state and local law enforcement agencies from sharing license plate reader data with out-of-state public agencies or federal entities.
The Press Democrat editorial also noted that investigators and civil liberties groups have documented California agencies illegally conducting searches on behalf of ICE officers. It cited the Marin County Sheriff’s Office’s 2022 settlement of a lawsuit after scans were forwarded to federal and out-of-state agencies.
In June 2026, the San Francisco Chronicle reported that San Francisco police found 299 improper searches of the city’s Flock license plate reader data conducted on behalf of federal and out-of-state agencies. The searches accounted for a tiny share of total inquiries, 0.005%, and police said they did not involve immigration enforcement or reproductive rights investigations. However, they still violated rules meant to protect the public.
The Press Democrat editorial also cited a Texas case in which police searched the national license plate reader network for a woman suspected of having an abortion. That example matters in California because reproductive rights may be protected here, but those protections mean little if local data is used in a national search system or if agencies ignore state limits on out-of-state sharing.
Individual misuse is also part of the record. The editorial noted that a former Costa Mesa police officer pleaded guilty in April to tracking romantic rivals, including an ex-girlfriend and his wife. The Orange County district attorney’s office said the former officer illegally accessed confidential law enforcement databases, including Flock, to track people unrelated to his duties.
That is how trust is lost.
Not always through one dramatic abuse.
Sometimes trust leaks away through small failures, unclear access, weak supervision, or a partner agency that does not follow the same rules.
California Attorney General Rob Bonta has warned law enforcement agencies that automated license plate reader data must be collected, stored, shared, and used in accordance with California law. His office has emphasized that agencies must have written policies on use and privacy to protect privacy and civil liberties.
That should be the floor, not the ceiling.
Guardrails must be clear
Santa Rosa appears to have taken some important steps.
The city says its Flock policies and usage statistics are available to the public through a transparency portal. The Santa Rosa Police Department states that the technology is used to capture objective evidence without compromising individual privacy.
The Press Democrat also reported that Santa Rosa’s cameras do not use facial recognition and do not identify people by race, gender, or other personal characteristics. The department prohibits use for immigration enforcement, personal reasons, harassment, intimidation, or use based solely on a protected class. Searches require officers to enter a reason, and data is retained for 30 days.
Those safeguards matter. But the community should expect more than assurances.
Santa Rosa should have a clear, public policy that explains which crimes or emergencies justify use of the system, who may access it, how searches are approved, how often audits are conducted, what happens when violations occur, and whether partner agencies can search local data.
The city should prohibit direct or indirect sharing with federal agencies, including those involved in immigration enforcement, except when clearly required by law and subject to a documented process.
It should publish regular public reports showing how often the system is searched, the general categories of cases it supports, how many hits lead to arrests or recoveries, how many searches are rejected or flagged, and whether any misuse occurred.
It should also invite public input before expanding the system or adding features such as live video, drones, audio detection, or artificial intelligence tools.
Public input is not a burden. It is how trust is built before there is a crisis.
SB 1013 offers a measured path
The Press Democrat editorial board urged lawmakers to pass Senate Bill 1013, authored by Sen. Sabrina Cervantes, D-Riverside. The bill would require agencies to delete plate scans after 30 days unless they are part of an active investigation or match an authorized hot list. Thirty days is already the standard in Santa Rosa.
The bill would also require clear records of who conducted a search and which specific case it was related to. It would bar new contracts that grant national databases default access to local scans.
The official bill text states that, beginning Jan. 1, 2027, new or updated ALPR contracts must ensure that no default access is granted to a national ALPR database and that an agency’s collected scans are not accessible to another agency by default. It would also require records to include a case file number or task force name that justifies the search.
That is the right direction.
This is not an argument for a statewide ban. It is an argument for statewide standards.
Local agencies should not have to reinvent privacy rules one city council meeting at a time. And the public should not have to wonder whether protections depend on which side of a city limit they happen to drive through.
As of Aug. 9, 2026, SB 1013 remains active in the Assembly Appropriations Committee, with a hearing scheduled for Aug. 13.
Santa Rosa should not wait for Sacramento to do everything. But if the state sets stronger standards, defending local trust becomes easier.
Sonoma County needs one clear standard
Santa Rosa should not have to answer this question alone.
Flock cameras are not limited by city boundaries. Public trust should not depend on which city line a driver happens to cross.
A car can pass through Santa Rosa, Rohnert Park, Windsor, Healdsburg, Petaluma, Sonoma or unincorporated county areas in a single afternoon. The rules governing that technology should be just as connected as the camera network itself.
That is why the Sonoma County Law Enforcement Chiefs’ Association should adopt a uniform countywide policy governing automated license plate readers.
The association already has a history of developing countywide law enforcement protocols. Its Law Enforcement Employee-Involved Fatal Incident Protocol was adopted in 1993 and revised over time to guide Sonoma County agencies during serious incidents involving law enforcement employees. The Sheriff’s Office also links to a 2024 community letter from the association addressing local law enforcement’s role in immigration and deportation operations.
That same collaborative structure should be used for Flock cameras.
A countywide policy should set a common floor, not a lowest common denominator. It should require 30 days of data retention unless the information is tied to an active investigation or an authorized hot list. It should require every search to include a case number, a documented purpose, and an identifiable user.
The policy should prohibit use for immigration enforcement, personal reasons, harassment, intimidation, First Amendment activity, or targeting people based on race, ethnicity, religion, gender, immigration status, or any other protected characteristic. It should also prohibit direct or indirect sharing with federal or out-of-state agencies unless clearly required by law and approved through a documented process.
This would align Sonoma County with the direction of SB 1013, which would require new or updated ALPR contracts to prevent default access to national ALPR databases and to ensure that one agency’s scans are not accessible to another agency by default.
The need for consistency is not theoretical. The Press Democrat editorial board reported that Santa Rosa’s 135 Flock cameras logged about 750,000 vehicles in July and that police searched those records nearly 1,000 times. It also noted that Windsor, Healdsburg, Rohnert Park, and Sonoma have cameras.
When a technology is used across multiple jurisdictions, the public deserves more than a patchwork of separate rules.
A countywide policy should also require annual public reports from each participating agency. Those reports should include the number of cameras in use, the number of vehicles scanned, the number of searches conducted, the broad categories of cases involved, the number of hits that led to arrests or recoveries, the number of searches audited, and whether any misuse was found.
This is not about making police work harder.
It is about making the rules clear before controversy forces the conversation. A uniform countywide policy would help agencies use the technology responsibly, provide officers with clear expectations and reassure residents that public safety tools are governed by public values.
A driver should not lose privacy protections merely by crossing from one Sonoma County community to another.
Trust is part of public safety
A community cannot separate technology from trust.
A license plate reader may help solve a crime. But if residents believe the same system could be used to track immigrants, protesters, abortion seekers, political opponents, or ordinary people going about their lives, the public safety benefit becomes fragile.
That is especially true in communities where government surveillance has not always been neutral.
Immigrant families know what it feels like to be watched. Communities of color know what it feels like to be overpoliced. People who speak out on controversial issues know how easily lawful activity can be treated with suspicion.
That history does not mean police cannot use modern tools.
It means they must use them with humility.
The question is not whether we trust one chief, one council, or one vendor. The question is whether the rules are strong enough to protect the community when leadership changes, political pressure mounts, or the technology expands beyond its original purpose.
That is where public safety and civil liberties intersect.
A balanced path
Santa Rosa does not have to choose between solving crimes and protecting liberties.
It can do both.
It can use Flock cameras to help locate stolen vehicles, find missing people, and develop leads in serious cases. It can also require short data retention, strict access controls, documented reasons for every search, independent audits, public reporting, and firm limits on data sharing.
It can support police officers in using technology responsibly while holding those who misuse it accountable.
It can recognize that residents driving through Santa Rosa should not feel invisible to public safety, but they should also not feel constantly watched.
That balance is not weakness.
It is democracy doing its job.
Why This Matters Today
Flock cameras matter because public safety and civil liberties are not competing values. They are promises a community makes to itself.
When technology helps solve serious crimes, recover stolen vehicles or locate missing persons, it can save lives and build trust. When the same technology collects the movements of hundreds of thousands of people and shares that data beyond public view, it can become something very different from what the public approved.
The risk is mission creep. A tool purchased for stolen cars and violent crime can gradually evolve into a system for tracking everyday life.
Santa Rosa should use effective public safety tools, but it should do so openly, carefully, and with enforceable limits. The goal is not to make police work harder. The goal is to strengthen public safety by ensuring that the tools used in our name reflect our values.
