Instances of police officers misusing Flock Safety automated license plate readers (ALPRs) are drawing increased scrutiny, with one report detailing how a police chief allegedly used the system to track his ex-girlfriend. This incident and others like it are prompting experts to advocate for stronger legal and technical safeguards on ALPR data.
The San Diego Voice & Viewpoint reported on October 1, 2026, that a former Braselton, Georgia police chief searched his ex-girlfriend's and her daughter's license plates approximately 600 times using Flock Safety's network. The officer was later charged with stalking and misuse of an ALPR before his death. This case is not isolated; at least 100 police department employees have been accused or charged with ALPR misuse, often involving tracking current or former partners.
Flock Safety states that these cases represent a small fraction of its large user base and that audit logs help identify misconduct. However, critics argue that the system's design itself facilitates such abuses, as unauthorized searches do not require hacking but rather involve users operating within the system's existing framework.
How does the ALPR system enable misuse?
Flock cameras capture vehicle license plates, locations, and distinguishing characteristics. This data is then searchable by police departments across the network, often without warrants or direct supervisory approval. This creates a powerful "search engine for movements," as one scholar described it.
One analysis of data copied from a single Flock camera revealed 1.6 million images and approximately 50,200 vehicles over 21 days. The software could detect people and even specific details like an American flag patch on a motorcycle.
Flock asserts that customers control their data. However, a police department might not know who is accessing its cameras if sharing is enabled. For example, U.S. Customs and Border Protection accessed over 80,000 cameras during a nationwide vehicle-tracking pilot without some departments' knowledge.
Misconduct is typically only discovered after the fact, and often by external investigations rather than internal audits. Indianapolis police, for instance, only began regularly auditing Flock searches after The Washington Post flagged questionable inquiries by an officer.
Flock has implemented changes, such as recommending shorter data retention periods (from 30 to seven days) and requiring case codes for searches. However, departments can still retain data longer, and emergency situations may bypass case code requirements.
What are the broader implications of ALPR data sharing?
The architecture of Flock's system allows local cameras to become part of a broader surveillance network. Agencies that did not purchase the cameras can still query them. This raises concerns about data sharing with federal agencies and in legally sensitive areas.
- Public records from Danville, Illinois, showed over 4,000 searches by federal agencies, including some with potential immigration enforcement focus, despite U.S. Immigration and Customs Enforcement having no direct contract with the city for Flock cameras.
- A 2026 study found nearly 12,000 immigration-related searches in records from eight college police departments, with federal agencies sometimes accessing campus camera data without campus officials' awareness.
- In one instance in May 2025, a Texas sheriff's office searched over 83,000 cameras for a woman who had self-managed an abortion. The search extended to Illinois, where state law prohibits sharing plate data to enforce other states' abortion bans.
These examples demonstrate how the platform makes camera data easy for secondary parties to use, difficult to monitor, and challenging to control once cameras are connected.
What legal protections exist for drivers?
The legal framework surrounding ALPR use remains in development. While some courts have held that retrieving a few images from a camera network does not require a warrant, the ability of these systems to create an archive of a person's movements raises Fourth Amendment concerns.
Recent Supreme Court decisions, like Carpenter v. United States (2018) and Chatrie v. United States (2026), have addressed the need for warrants for historical cellphone location data. These cases highlight concerns about systems that can reconstruct past movements, a capability shared by ALPR networks.
Experts suggest that internal controls alone are insufficient to prevent misuse. Independent or judicial oversight is needed. Proposed safeguards include:
- Requiring judicial authorization, such as a probable-cause warrant, for retrospective regional or national searches, with an emergency exception.
- Implementing technical access controls to restrict immigration and reproductive health-related searches.
- Enforcing the deletion of data after a short period.
- Moving to an opt-in model for interstate data sharing, rather than the current default.
- Conducting independent audits of search logs and device security.
As a driver, understanding where ALPRs are deployed and how your data might be used is essential. You can learn more about these systems and their impact on privacy at /learn and see known camera locations on our /map. The ongoing legal and policy discussions aim to establish clearer rules for ALPR use, which could impact how your vehicle's movements are tracked in the future. The debate continues on how to balance public safety benefits with individual privacy rights, especially concerning the growing network of surveillance cameras. The next steps will likely involve further legal challenges and policy debates aimed at creating enforceable limits on ALPR data access and retention.
