William C. Copp, police chief in Holiday Hills, Illinois, was arrested on June 18, 2026, and charged with official misconduct for using the Flock license plate tracking system and a state database to illegally track six acquaintances, including three former romantic partners and one ex-partner's new partner, whose plate he queried 140 times.
William C. Copp, police chief of Holiday Hills, Illinois, was arrested June 18 on two counts of official misconduct after prosecutors say he used the Flock license plate tracking system and the state LEADS database to track six people he knew. Three of the six were women with whom Copp had past romantic relationships. He also tracked the ex-partner of one woman, querying that man's license plate 140 times over several months, 86 of them outside work hours. In September 2025, Copp left a threatening voicemail identifying himself as police and telling the man not to contact his ex-girlfriend.
The case is the latest in a series of similar abuses. Since November 2025, at least three other law enforcement officials have been caught using Flock data to stalk spouses or ex-lovers. The Judicial Institute, which is suing Flock, said there are at least 18 related lawsuits nationwide as of mid-2026 and called that number an undercount. Critics argue the system's warrantless access invites misuse.
