Privacy Advocates Urge California to Remove Covert License Plate Readers

2/11/2026, 11:19:44 AM

Covert Surveillance Network Under Scrutiny

More than two dozen privacy and advocacy organizations are urging California Governor Gavin Newsom to dismantle a network of covert license plate readers deployed across Southern California. These groups, including the Electronic Frontier Foundation and Imperial Valley Equity and Justice, argue that the devices contribute to a controversial U.S. Border Patrol predictive domestic intelligence program that monitors travel patterns for suspicious activity. In a letter sent to Newsom, the organizations requested an investigation into the permits for these devices, their removal, and the revocation of any relevant permissions.

An Associated Press investigation revealed that the U.S. Border Patrol, part of U.S. Customs and Border Protection, has concealed license plate readers within ordinary traffic safety equipment. The data collected is used in a predictive intelligence program that scans millions of drivers nationwide, aiming to identify and detain individuals based on their travel patterns. The letter from advocacy groups highlighted that approximately 40 license plate readers have been identified in San Diego and Imperial counties, with many hidden in construction barrels.

Legal and Ethical Concerns

The use of these license plate readers has raised significant legal and ethical questions. The groups noted that the Border Patrol and the Drug Enforcement Administration (DEA) have applied for permits to place these readers along state highways, with the DEA sharing its data with the Border Patrol. The program has been criticized for its potential violation of Fourth Amendment rights, which protect against unreasonable searches and seizures. Courts have generally upheld the collection of license plate data on public roads but have limited warrantless access to other tracking data that could reveal sensitive information about individuals' movements.

Impact on Individuals

The implications of this surveillance program have been illustrated through specific cases involving California residents. In one incident from 2024, a Border Patrol agent stopped a driver based on travel data indicating an unusually long trip from the U.S.-Mexican border to Oceanside, California. The agent claimed that such delays are often associated with smuggling activities. Another case in 2023 involved a woman detained at an internal checkpoint after taking a circuitous route between Los Angeles and Phoenix, with law enforcement alleging she was involved in unlawful immigrant smuggling.

Official Responses

The California Department of Transportation and Governor Newsom's office did not respond to requests for comment regarding the surveillance program. The Border Patrol has previously stated that its use of license plate readers is governed by strict policies and is aimed at identifying threats and disrupting criminal networks. The DEA, while acknowledging the use of such tools, refrained from discussing specific investigative techniques.

Criticism from Advocacy Groups

Privacy advocates have expressed concerns about the implications of this surveillance technology. They argue that the use of license plate readers and predictive algorithms represents a form of sweeping surveillance that raises constitutional issues. The organizations emphasized that courts are increasingly recognizing the potential violations of privacy rights associated with these technologies.

Conclusion

As the debate over the use of covert license plate readers continues, privacy and advocacy organizations are calling for transparency and accountability in surveillance practices. The outcome of this situation may have broader implications for privacy rights and law enforcement practices in California and beyond.
