Objects and attributes
This diagram shows the system analyzing objects, including people, and assigning attributes that can be stored and searched.
Evidence, not speculation
Four reasons Casa Grande needs Flock oversight now.
The concern is not abstract. Flock's own patent describes more than plate reading, a Casa Grande email lists camera monitoring of a student protest at City Hall, the public-facing policy appears to conflict with local reporting about traffic-enforcement use, and the released audit logs do not let residents meaningfully verify police use.
What is wrong?
Patent
Flock is not just license plate reading
Flock's own patent describes video analysis that can identify people, objects, attributes, locations, and searchable records.
Protest monitoring
A Casa Grande email lists monitoring a student protest as a camera-system win
The January 30, 2026 email also describes locating individuals, identifying involved parties, and identifying theft suspects, despite public assurances that the system tracks vehicles rather than people.
Traffic enforcement
The city-linked policy says no traffic enforcement. Local reporting says Safe City data was used in a traffic crackdown.
Casa Grande links residents to a Flock transparency page saying the system will not be used for traffic enforcement, while local reporting describes CGPD using Safe City data during a traffic-enforcement detail.
Audit logs
The audit logs do not provide the accountability residents were promised
The released logs are heavily redacted and contain missing, generic, or placeholder reasons and case numbers that make public review difficult.
Evidence 1 / Patent scope
Flock's own patent describes far more than license plate reading.
The patent describes identifying people and objects, classifying attributes, storing video records with time and location, and searching those records by object and attribute data.
Why the patent matters
Companies patent technology to protect intellectual property they are using, building, or preparing to commercialize. A patent is not proof that every feature is active in Casa Grande today, but residents should treat these capabilities as real product direction, not speculation. With AI moving quickly across industries, this technology may already be in use elsewhere or close to deployment.

People and objects in video
The patent describes analyzing video to identify people and objects, not just vehicles.

Person attribute examples
The patent describes classifying people by sex, race, clothing, and physical characteristics.

Attribute and location search
This shows the system can search video for specific types of people based on attributes and location.

Searchable video database
The system stores and allows searching of video based on attributes, not just time and location.

Evidence 2 / Protest monitoring
The city’s own email lists monitoring a student protest as a camera-system win.
Casa Grande points residents to public assurances that Flock tracks vehicles, not people, and is not used to track individuals. Yet the January 30, 2026 police email lists “Monitoring of a student protest at City Hall” among its notable wins from the past ten days.
Monitoring a peaceful protest is precisely the kind of protected activity those assurances are meant to rule out — here it is logged as a success. The same email counts tracking people as more wins: locating specific individuals, identifying “involved parties,” and “monitor[ing] activity” before patrol arrived. Officials say the system does not track individuals while celebrating exactly that, which is why residents need enforceable rules that address people and protest activity, not just vehicle plates.

Evidence 3 / Traffic enforcement
The public policy says no traffic enforcement. Local reporting describes Safe City data being used in a traffic detail.
The Casa Grande city website links to the Flock transparency portal, where the public-facing policy says Flock will not be used for traffic enforcement.
PinalCentral reported that CGPD used Safe City real-time data from cameras and drones during a two-day traffic enforcement detail that resulted in more than 60 arrests and citations.
Evidence 4 / Audit logs
The audit logs do not provide meaningful public accountability.
Casa Grande residents were told audit logs would make Flock use reviewable. The released logs make that promise hard to verify.
Audit trail promise
“Anybody wants to question who's looking at what. We have an audit trail. This system has an audit trail and they have to have a case number to look at it.”
That promise is exactly why the released records matter. When the audit trail was requested, the city redacted all license plate numbers, stating it was for privacy. Without license plate data, the public cannot tell whether searches matched a real case number, official police need, or policy limits. It makes it impossible for residents to know from the released records whether the system is being misused.
Source: Police chief audit trail statementWhat the released logs show
Residents were promised accountability. The records do not let the public verify it.
Redactions block public verification
The city released audit logs with license plate information redacted, which prevents residents from checking whether a search matched a specific incident, complaint, or official need.
Many searches lack meaningful case information
The logs include entries with missing case numbers, “none,” placeholder-looking values like “2025- 00000000,” and generic reasons that do not let the public verify official police business.
Reasons are often vague or incomplete
Entries include reasons such as “missing,” “investigation,” numeric shorthand, or broad categories that do not explain why the search was necessary.
Some searches reach very wide networks
The logs include searches across hundreds of networks and thousands of devices, which makes strict case numbers and specific reasons even more important.
The logs themselves include traffic-related uses
The January 2026 audit includes entries labeled “Traffic Infraction - Suspicious Activity” with case number “none,” which in our view reinforces the concern that the public policy and recorded use do not clearly match.
Source documents
Monthly Flock audit logs released by the city
These are the records residents are supposed to use to hold the system accountable. They should show who searched, why, and whether the search was tied to official police business.
Linked audit-log PDFs are presented as source records released for public review. Readers should check the records directly and report any correction request to [email protected].
Bottom line
Casa Grande residents deserve enforceable rules, not vague assurances.
The evidence supports warrants where appropriate, stronger retention and sharing limits, independent audits, public reporting, and real consequences for misuse.
