While Flock claims its system tracks vehicles, not people, the documented record of police chiefs stalking ex-partners through Flock shows otherwise. When the most experienced, highest-ranking officers in law enforcement, the people most responsible for enforcing the rules, demonstrate ongoing abuses, the answer is the same courts have given for each generation of powerful tracking technology: require a warrant first.
The police chief of Holiday Hills, Illinois, and a part-time officer at Prairie Grove Police Department, was arrested June 18, 2026, and charged with two counts of official misconduct, a Class 3 felony.
Prosecutors alleged he used Prairie Grove’s Flock license plate reader system and the Illinois State Police LEADS database to track six people he knew personally.
Three of those people were women the chief had been in romantic relationships with, according to prosecutors at his arraignment. He also tracked an ex-boyfriend of one of those women, running that man’s plate 140 times over several months, a figure the protective order petition put at 178, with 86 of those searches conducted while off duty.
