Wisconsin law enforcement agencies used Flock Safety automated license plate reader cameras more than 100 times to track a Navy veteran who lawfully recorded a traffic stop, according to documents obtained through public records requests. The case has drawn national attention to questions about police surveillance practices and the rights of citizens to document officer conduct.
Flock Safety cameras are fixed-location devices that automatically capture license plates, timestamps, and vehicle descriptions. Law enforcement agencies across the country have deployed the technology to assist in criminal investigations. Wisconsin's use of the system against a veteran who was exercising his right to record police interactions has raised concerns among civil liberties groups about potential overreach.
What the Right Is Saying
Law enforcement supporters argue that Flock cameras serve legitimate crime prevention purposes and have helped solve property crimes and locate missing persons. The Wisconsin Police Chiefs Association has emphasized that license plate readers are a modern tool that helps officers do their jobs more effectively. "These systems help us identify stolen vehicles, locate fugitives, and investigate crimes," an association spokesperson said.
Conservative commentators have noted that the veteran was not charged with any crime related to recording police, suggesting law enforcement's use of surveillance in this case may have been appropriate for investigating potential threats or harassment of officers. Some argue that citizens filming traffic stops could be attempting to provoke reactions from police, and investigators should have tools to assess patterns of behavior.
Others on the right who favor limited government say while they take privacy concerns seriously, the focus should remain on whether any laws were broken rather than the technology itself. They contend that proper policies and oversight, not bans on surveillance tools, are the appropriate response to potential abuses.
What the Left Is Saying
Civil liberties advocates argue that the case represents a troubling expansion of surveillance power. The ACLU of Wisconsin said the repeated tracking of someone for lawfully filming police raises serious First Amendment concerns. "Citizens have a constitutional right to document police activity in public spaces," an ACLU spokesperson stated in a press release, adding that using surveillance infrastructure to monitor people exercising this right could have a chilling effect on lawful speech.
Privacy advocates contend that automated license plate readers, while sometimes useful for solving crimes, create extensive databases of Americans' movements without their knowledge or consent. They argue that law enforcement should not be able to track individuals retroactively over extended periods based solely on their presence near a traffic stop. The Electronic Frontier Foundation has noted that such capabilities could be used to identify and surveil journalists, activists, and others engaged in constitutionally protected activities.
Progressive criminal justice reformers say the case exemplifies how surveillance technology disproportionately impacts veterans and communities of color. They are calling for stricter regulations on when and how police can access ALPR data, including requiring warrants for tracking individuals based on their exercise of First Amendment rights.
What the Numbers Show
Flock Safety reports that its cameras are deployed in more than 3,000 communities across 43 states as of early 2026. The company processes millions of license plate scans daily, according to its website. Wisconsin has multiple municipal and county agencies using the system, though exact deployment numbers are not publicly disclosed.
A 2024 report from the Brennan Center for Justice found that ALPRs can generate hundreds of thousands of scans per year in mid-sized cities, creating massive databases of vehicle locations. Research has shown that such systems can locate a person's vehicle with approximately 95% accuracy within a given geographic area over time.
Studies on citizen recording of police have consistently found that such documentation helps hold officers accountable and can reduce use-of-force incidents. A 2023 study published in the Journal of Quantitative Criminology found no evidence that increased civilian recording leads to officer safety risks, contradicting claims made by some law enforcement groups.
The Bottom Line
The Wisconsin case highlights ongoing tensions between law enforcement surveillance capabilities and constitutional protections for speech and privacy. Civil liberties groups are pushing for legislation requiring warrants before police can track individuals using ALPR data, particularly when the investigation is related to First Amendment activity. At least 14 states have introduced such bills in recent years with varying levels of success.
What comes next: Wisconsin lawmakers have scheduled hearings on potential reforms to the state's ALPR statutes. Flock Safety has stated it does not comment on specific law enforcement investigations but emphasized that its customers determine how to use the technology within legal bounds. Advocates on both sides say they will be watching the legislative session closely for signs of where consensus might emerge.
