Key Takeaways
- Flock Safety’s solar‑powered, automated license‑plate readers (ALPRs) are deployed on roughly 80,000 street corners nationwide and log billions of plate reads each month.
- At least two dozen police officers have been caught using Flock data to stalk romantic partners or ex‑partners; most were criminally charged, resigned, or lost their jobs.
- Recent reports (early 2025) show new misuse cases in Illinois, South Carolina, Texas, California, Georgia, and Wisconsin, indicating a widening pattern of abuse.
- Privacy advocates, including the ACLU, warn that ALPR tracking can reveal deeply personal information and constitutes a serious threat to civil liberties when misused.
- Growing public backlash has led dozens of municipalities to cancel Flock contracts, while grassroots groups map camera locations and demand greater oversight.
Introduction to Flock Safety’s Technology
Flock Safety manufactures compact, solar‑powered automated license‑plate recognition (ALPR) cameras that weigh less than three pounds and are designed to blend unobtrusively into urban environments. Installed on streetlights, utility poles, and other infrastructure, each unit continuously captures images of passing vehicles, extracts license‑plate numbers, and timestamps the data. The company claims its network now encompasses about 80,000 devices across the United States, collectively logging billions of plate reads every month. Flock markets the system as a force‑multiplier for law‑enforcement agencies, promising faster crime solving and improved public safety through real‑time vehicle tracking.
Widespread Adoption and Business Success
Since its founding, Flock Safety has experienced explosive growth, attaining an estimated valuation of $8.3 billion. The firm’s success stems from a subscription‑based model that provides police departments with access to a cloud‑based analytics platform, allowing officers to query historic plate data, set up alerts for specific tags, and generate reports on vehicle movements. This business approach has facilitated rapid deployment: cities of all sizes have signed contracts, attracted by the promise of low‑maintenance hardware and the ability to “have a camera on every corner,” as CEO Garrett Langley has publicly stated.
Documented Misuse by Police Officers
Despite the technology’s intended purpose, numerous investigations have revealed that officers are exploiting Flock data for personal reasons. In early 2025, Milwaukee Police Officer Josue Ayala was found to have searched the license‑plate number of a romantic interest over 200 times within two months, also probing his partner’s former lover. After being charged with misconduct, Ayala resigned and received a year of probation. Notably, the officer assigned to investigate Ayala’s case, Tehrangi Chapman, subsequently engaged in the same behavior—using the ALPR system to track individuals in his own life—leading to additional charges of “misuse of GPS information.”
National Pattern of Abuse
The Institute for Justice, a libertarian public‑interest law firm, has identified at least 24 comparable incidents nationwide over the past two years in which police officers employed Flock or similar ALPR systems to surveil romantic partners, exes, or acquaintances. In nearly every case, the offending officer faced criminal charges, termination, or forced resignation. The pattern suggests that the technology’s accessibility—combined with inadequate internal controls—creates a temptation for personal surveillance that law‑enforcement agencies have struggled to curb.
Recent Surge in Reports (2025)
The first months of 2025 have seen a fresh wave of allegations. Media outlets have reported misuse incidents involving officers in Illinois, South Carolina, Texas, California, Georgia, and Wisconsin. In each instance, the officer was accused of querying Flock data to monitor a current or former romantic interest, resulting in job loss or criminal proceedings. These reports underscore that the problem is not isolated to a single jurisdiction but reflects a systemic vulnerability in how ALPR data is accessed and audited.
Privacy and Civil‑Liberties Concerns
Chad Marlow, senior policy counsel at the American Civil Liberties Union (ACLU), emphasizes that ALPR tracking can expose intimate details about a person’s daily life—places of worship, medical visits, political gatherings, and more—simply by following a vehicle’s movements. Marlow warns that “the tracking of an individual vehicle… can reveal very deeply personal and private information,” describing Flock at its most dangerous when used for non‑investigative, personal surveillance. Earlier research by the ACLU found that in Maryland, fewer than 0.005 % of scanned plates were linked to serious crimes, highlighting the vast amount of innocuous data collected.
Expanding Use Beyond Traditional Policing
Beyond criminal investigations, Flock’s ALPR network has been repurposed for immigration enforcement and monitoring individuals seeking reproductive health services. Agencies have used the system to track vehicles crossing state lines without warrants, raising constitutional concerns about unreasonable search and seizure. The breadth of these applications amplifies the potential for abuse, as officers with access to the platform can query data for virtually any motive, personal or professional.
Growing Public Opposition and Municipal Pull‑Backs
Activist groups such as DeFlock have responded by publishing interactive maps that pinpoint Flock camera locations, empowering citizens to scrutinize surveillance density in their neighborhoods. In 2025 alone, at least thirty municipalities terminated their Flock contracts amid privacy protests and fears of misuse. Flock Safety’s CEO Garrett Langley once labeled critics “terroristic,” a remark he later apologized for, indicating a shifting tone as pressure mounts.
Future Outlook and the Push for Reform
Marlow predicts that opposition to government surveillance will continue to intensify, noting that “in these incredibly divisive political times, we’re actually seeing the rare issue that unites Americans: opposition to government surveillance.” He anticipates the movement will expand, prompting legislatures and police departments to adopt stricter audit trails, limit data retention, and impose independent oversight on ALPR usage. Without such reforms, the risk remains that a tool designed to enhance public safety will instead become a conduit for personal intrusion and erosion of civil liberties.
