Police describe new license-plate reader use after cameras help stop out-of-jurisdiction shooting suspect
Summary
Police announced the activation of automatic license-plate-reader capability on June 1 and said the technology is being used to support investigations of serious crimes, with data retained for 30 days and limited administrative access.
Village police told trustees they activated automatic license-plate-reader capability on June 1 and described the limited, crime-focused uses of the technology after it helped a regional response in which officers apprehended a shooting suspect.
The matter affects residentsprivacy and public safety because ALPR systems collect vehicle-plate reads that, if used broadly, can raise civil-liberty concerns. Police described the rules they will follow for queries and retention.
A police official identified in the meeting as the police chief explained the departments policy and operational use. The chief said the ALPR cameras and subscriptions are under contracts the department recently executed; data from ALPR cameras are retained for 30 days in the vendor system and can be queried for major crimes, kidnappings, fugitives and other serious investigations. "We do not use them to find people who have outstanding parking tickets or that don't have a driver's license," the chief said. The chief added that the cameras support multi-agency information sharing through vendor integrations and hot-sheet alerts from state databases.
The chief described an operational example: this past weekend a nearby shooting prompted an alert. Because the villages ALPR-equipped vehicle registered a hot-sheet match, officers were able to stop the vehicle, apprehend the suspect and recover a firearm; the chief called that a success story tied directly to the new capability.
Trustees asked about possible use for immigration enforcement. The chief said the department does not use ALPRs for immigration enforcement and that administrative controls limit which queries and hot sheets are permitted. The chief repeated that the system is not being used for low-level administrative checks and said the department retains control over what the cameras are activated to search for.
Staff and trustees said they will present the ALPR contract and operational practices to the board as needed. The department emphasized training and policy controls to limit misuse and preserve civil-liberty protections.
