Multiple U.S. police officers have been arrested for
using Flock AI license plate reader systems to stalk romantic partners, with
investigators identifying at least 18 confirmed cases nationwide. A June 2026
report from Tom’s Hardware brought renewed attention to this pattern, which
sits alongside separate revelations about unauthorized data sharing, public
data leaks, and AI misreads that have put Flock Safety under intense scrutiny
this year.
What Is Flock Safety and Why Are These Misuse Cases
Alarming?
Flock Safety is an Atlanta-based company that sells automated license plate reader (ALPR) cameras to police departments, homeowners associations, and municipalities across the country. The cameras capture plate numbers, vehicle descriptions, and location data, feeding that information into a searchable database that law enforcement can query in real time.
The system is now one of the most widely deployed surveillance tools in American policing. That scale is exactly what makes the pattern of misuse documented in the Flock AI License Plate Readers: Police Misuse Cases Emerge in June 2026 coverage so concerning.
Why it matters: When officers can query a system that tracks where any vehicle has been, that power can easily be turned against private citizens, including ex-partners, neighbors, or anyone an officer wants to monitor without a warrant.
How Are Officers Misusing Flock to Stalk Romantic Partners?
The core abuse is straightforward and deeply troubling. Officers log into the Flock system using their legitimate department credentials, then run searches on vehicles belonging to people they have personal relationships with, often ex-partners or people they are in conflict with outside of work.
According to a 2026 report from Tom’s Hardware, investigators have confirmed at least 18 such cases across multiple U.S. jurisdictions [7]. Officers in these cases were arrested, fired, or placed under investigation after audits revealed searches that had no legitimate law enforcement purpose.
The pattern looks like this:
- Officer runs repeated queries on a specific plate number
- Searches occur outside normal duty hours or without an associated case number
- The plate belongs to a person the officer knows personally
- No criminal investigation justifies the search
This is not a one-state problem. Cases have surfaced in departments of varying sizes, from large urban forces to smaller suburban agencies [8][9][10].
“The same database designed to catch car thieves can become a real-time tracking tool for an abusive officer. That’s not a hypothetical. It’s already happened at least 18 times that we know of.” — synthesized from reporting at Tom’s Hardware [7] and Verity News [8]
What Did San Francisco’s Audit Reveal About Unauthorized Searches?
San Francisco Police Chief Derrick Lew disclosed on June 1, 2026, that an internal audit found 299 improper searches of the city’s Flock ALPR data. These searches were conducted on behalf of federal and out-of-state law enforcement agencies over approximately one year [1].
SFPD characterized the 299 queries as roughly 0.005% of all Flock inquiries during the period. But the department also acknowledged this is likely a “statewide issue” affecting other California agencies using Flock, not just San Francisco [1].
What this means in plain terms:
- Local departments may be running searches for federal agencies, including immigration enforcement, without formal authorization
- The data is more portable and shareable than most residents realize
- Local elected officials and oversight bodies may not know this sharing is happening
This disclosure is expected to accelerate scrutiny of how Flock data flows beyond local control, particularly to federal entities whose enforcement priorities may not align with community values [1][3].
How Did 600,000 Unauthorized Searches Happen in Mountain View?
A separate incident in Mountain View, California, revealed that more than 250 external organizations had conducted roughly 600,000 searches using that city’s Flock data, all without local officials’ consent [6].
When city leaders discovered the scope of the unauthorized access, they deactivated 30 Flock cameras in February 2026 [6]. That’s a significant step, and it signals that at least some local governments are willing to pull the plug when they find out what’s actually happening with their data.
The Mountain View case also illustrates a structural problem: Flock’s network architecture may allow data from one city’s cameras to be queried by agencies far outside that city’s jurisdiction, without any notification to local officials.
Did Flock’s System Actually Leak Data Into Public Search Results?
Yes. Privacy advocates in Northern Colorado discovered that police license plate searches generated by Flock were appearing in public search engine results [6]. The exposed data included full plate numbers, case IDs, vehicle descriptions, and the stated reasons for investigation, including notations like “GTA” (grand theft auto).
Flock acknowledged that around 70 URLs from 2024 to 2025 had been indexed by search engines before the company moved to remove them [6].
What was exposed:
| Data Type | Risk Level |
|---|
| Full license plate numbers | High |
| Case IDs and investigation reasons | High |
| Vehicle descriptions and colors | Medium |
| Location and timestamp data | High |
A public audit-log project called “Have Been F?” has documented 184,195,968 Flock searches covering 4,437,098 license plates [6]. That number alone illustrates the scale of what’s at stake if security or access controls fail.
Are Flock Cameras Also Making Mistakes That Harm Innocent People?
Separate from the misuse and data-sharing problems, Flock cameras have been documented misreading license plates, leading to innocent drivers being stopped by police [4][5]
When a camera misreads a plate and flags it as stolen or wanted, officers may conduct a traffic stop on a completely innocent driver. These stops can be frightening, especially for Black and Brown drivers who already face disproportionate police contact.
Business Insider and a Morristown, Tennessee, news outlet both reported on this pattern in early 2026 [4][5]. The AI is not infallible, and the consequences of its errors fall on ordinary people.
What Is the Broader Privacy and Civil Liberties Concern?
The cases documented under the Flock AI License Plate Readers: Police Misuse Cases Emerge in June 2026 umbrella are not isolated glitches. They reflect a systemic gap between how surveillance technology is sold to the public and how it actually operates.
Communities are told these cameras catch criminals. What they’re often not told:
- The data may be shared with federal immigration agencies [3]
- Outside organizations can potentially access local data without consent [6]
- Individual officers can query the system for personal reasons with limited oversight [7][8]
- The AI can misidentify plates and trigger stops of innocent people [4][5]
Several municipalities have already canceled or paused their Flock contracts, citing immigration surveillance concerns and data privacy risks [3].
Conclusion: What Can You Do About This Right Now?
The pattern documented in the Flock AI License Plate Readers: Police Misuse Cases Emerge in June 2026 coverage is a community accountability issue, not just a tech story. Here in upstate New York and across the Mohawk Valley region, many local governments are evaluating or already using ALPR technology. Residents have a right to know what’s happening with that data.
Actionable steps for concerned citizens:
- Ask your local government directly. File a public records request asking whether your city, town, or county uses Flock Safety cameras and who has access to the data.
- Attend a city council or county legislature meeting. Put surveillance oversight on the agenda. Demand written data-use policies before any new contracts are signed.
- Contact your state representative. New York State has active conversations about surveillance oversight legislation. Your voice matters in that debate.
- Support local journalism. Stories like this surface because reporters dig. Subscribe to and share outlets doing this work.
- Talk to your neighbors. Community awareness is the first line of defense against unchecked surveillance expansion.
Police reform and criminal justice reform depend on communities staying informed and engaged. The technology moves fast. Oversight has to keep up.

Have any cities canceled their Flock contracts?
Yes. Several municipalities have canceled or paused Flock contracts, primarily citing concerns about immigration surveillance and data privacy [3].
Is this a problem specific to one state?
No. Misuse cases have been documented across multiple U.S. jurisdictions, and the San Francisco audit suggests the data-sharing problem may be widespread across California and potentially other states [1][7].
