Chicago police can search some license plate records collected by cameras they do not own. That might be helpful when officers are looking for a missing person or a vehicle involved in a shooting. It also raises an awkward question: who makes sure those searches are legitimate when another organization controls the camera system?

On October 23, 2026, the Chicago Police Department acknowledged that its internal affairs investigators were reviewing whether officers misused access to outside license plate reader networks. The department also announced tighter access controls and a review of earlier searches. It had not announced findings of wrongdoing from that review.

At the same time, Chicago opened a public comment period on proposed rules that could change how officers search outside databases. Comments were scheduled to close November 12. Those proposed rules are not the same as a final policy already in effect.

How can Chicago officers use cameras the city does not own?

A camera installed by one police department can help another department if the two agree to share access. That is useful when a vehicle crosses city limits. But it also means the officer making a search might work hundreds of miles from the pole where the plate was photographed.

Chicago operates its own license plate reader systems and has used the technology for years. It does not have a direct Flock Safety camera contract for the police department’s own fleet. Still, FOX 32 Chicago reported that officers performed more than 23,000 searches of Flock data during a three month period through a third party arrangement. The figure describes reported search activity, not 23,000 misconduct cases.

This is why saying that a city has no Flock cameras can be misleading. A department may not own the equipment but may still be able to look up information collected by someone else’s cameras. The distinction between owning data and accessing data is central to Chicago’s investigation.

What is Chicago investigating?

The department’s Bureau of Internal Affairs is examining possible misuse and auditing past searches of outside systems, according to WTTW’s October 23 report. Neither the department nor the news accounts reviewed here established that particular Chicago officers had committed violations. The investigation itself is not a finding of guilt.

The department has already restricted access to external systems to people whose duties require it. According to the Chicago Sun-Times, each of the department’s five bureaus also must designate someone to oversee license plate reader use. Those are immediate steps, distinct from the additional changes proposed in the draft directive.

A proper audit asks more than how many searches were performed. It asks who searched, what case justified the lookup, whether records were shared and whether anybody noticed a questionable search. Without those answers, a promise that access is limited is difficult for the public to evaluate.

What would the proposed rules change?

The draft calls for individual login credentials that cannot be shared among officers. It would require a documented law enforcement purpose for each lookup and add a case number, offense type and explanation when someone searches an outside network. Proposed monthly audits would help supervisors catch searches that do not fit the rules.

The draft would also route requests for external access through the city’s Office of Public Safety Administration. Possible consequences for violations range from losing database access to a referral for criminal prosecution. The Sun-Times described those proposals on October 26; they should not be presented as penalties already imposed on a named officer.

Another proposed change is easy to misunderstand. FOX 32 reported that Chicago would shorten the normal retention period for its own plate reader data from 365 days to 30 days. That proposed limit applies to city owned systems, not automatically to Flock records stored by outside agencies. It would still need to be put into effect, with any lawful evidence exceptions considered.

Why does Illinois care who can search the records?

In August 2025, the Illinois Secretary of State’s office reported that a statewide audit found improper access to Illinois Flock data by federal immigration authorities. That finding about the vendor’s sharing controls was not a finding that Chicago police carried out the searches under review today.

More recently, several officers in Chicago suburbs have faced allegations or charges involving unauthorized plate reader searches. Those are separate cases, not proof that Chicago’s own internal investigation will uncover the same behavior. Still, they show why an audit needs a way to detect improper queries instead of relying solely on users to follow the policy.

The Chicago department argues that license plate readers assist investigations into homicides, shootings and people at high risk who have gone missing. The value of a timely vehicle lead can be real. It does not follow that every search is justified, or that a database search proves who was driving a particular vehicle.

Are Chicago’s bus and bike lane cameras the same thing?

No. The City Council voted October 14 to make its Smart Streets enforcement program permanent and expand it citywide. Those cameras are used to document particular bus lane and bike lane violations, with rules limiting other uses of their footage.

That traffic enforcement program is separate from the police investigation into searchable records held by outside license plate reader networks. Both may photograph plates, but purpose, access permissions and retention rules can differ. It would be a mistake to treat a vote about bus lane tickets as approval of unrestricted police searches.

What should Chicago residents watch next?

First, whether the proposed directive is finalized after the November 12 comment deadline, and which provisions survive. Second, whether the department releases meaningful results from its audit. Third, whether officers and supervisors can actually demonstrate that access logs include every type of search, including searches of databases outside the city.

That last question has a useful Illinois comparison. In Elgin, police audited more than 14,000 license plate reader log records and found an important gap in search logging. Chicago is looking at a different problem: who may reach outside records in the first place. Both stories show why a camera policy must be matched by an audit that works in practice.

The next important news from Chicago will not be another statement that license plate readers are helpful or controversial. It will be what the audit actually finds, what rules are adopted and whether the public can see enough to judge how they are enforced.
