Flock, a provider of automated license plate reader technology, faces increasing public criticism and planned vandalism on Halloween 2026 after reports of police misuse and a series of stalking incidents. The company has long been criticized for retaining location data from drivers who are not suspected of wrongdoing, and recent disclosures of law enforcement officers using the system to track individuals have heightened scrutiny. CEO Garrett Langley apologized publicly after a woman was stalked using Flock’s system, following a Washington Post report that documented 46 cases of police officers allegedly abusing access. Flock announced changes, including reducing standard data retention from 30 days to seven days, introducing an optional audit feature that will become mandatory by year‑end, and adding restrictions that allow agencies to limit searches related to immigration enforcement. The company also said more than one‑third of its customers have voluntarily enabled the audit tool. In August 2025, a probable‑cause affidavit revealed that a police officer in Haines City, Florida, searched for his estranged wife’s license plate 717 times between September 2024 and June 2026, leading to his suspension on paid leave. Social media users have organized a Halloween campaign encouraging participants to disable nearby ALPR cameras, wear costumes and conceal identities, with more than 36,500 posts on X reported over two days. Flock declined to comment beyond an automated response stating that its media team was unavailable. The company has not disclosed any specific counter‑measures, and it remains unclear how the Halloween‑focused campaign will affect its operations.
