Former Joliet police lieutenant indicted over alleged personal use of Flock ALPR system

A Will County grand jury indicted former Joliet Police Lt. Jeremy Harrison, 50, on charges of computer tampering and official misconduct for allegedly using the Flock Safety automated license plate reader system for his own benefit. The Illinois State Police announced the charges, which followed an October 2025 referral from the Joliet City Inspector General asking the state agency to investigate Harrison. The charges are allegations, and no finding of guilt has been reported.

Why this matters

Audit and referral mechanisms, rather than the ALPR system's own safeguards, are what reportedly surfaced the alleged misuse — a point of reference for communities weighing how queries of license plate databases are monitored.
