Ex-Joliet police lieutenant charged with felonies over alleged Flock camera misuse

First reported: October 7, 2026 · 3 sources

Illinois State Police said former Joliet police lieutenant Jeremy Harrison has been charged with computer tampering and official misconduct after an investigation into alleged misuse of the city's Flock license plate reader system. ISP alleged that Harrison used the ALPR system for personal benefit. The investigation began with a complaint filed by Joliet's inspector general last year, according to ISP. The charges are allegations and have not been tested in court.

Why this matters

Criminal charges against a supervising officer over ALPR queries test whether existing Illinois statutes — computer tampering and official misconduct — can be used to hold police accountable for searches made for personal reasons, an area where legal gaps have been raised.
