WASHINGTON (AP) — Several Democratic lawmakers are challenging the legitimacy of a U.S. Border Patrol predictive intelligence program that targets and detains drivers based on perceived suspicious travel patterns.

Senator Ed Markey of Massachusetts described the license plate reader initiative as an “invasive surveillance network,” highlighting its potential violation of individuals' privacy and civil rights. He expressed concerns about the program mirroring practices of authoritarian regimes, warning it erodes fundamental rights and sets a dangerous precedent for government power.

An Associated Press investigation disclosed that the U.S. Border Patrol maintains a nationwide program tracking millions of drivers to identify those considered suspicious. The program includes sensor technology to record license plate data, often camouflaged in standard traffic equipment, and shares information with local law enforcement for traffic stops based on minor infractions.

Markey urged the Border Patrol to provide details on the use of these plate readers, echoing sentiments from other lawmakers. Representative Dan Goldman of New York questioned how the program aligns with Fourth Amendment protections against unreasonable searches, emphasizing that driving alone should not constitute probable cause for detention.

Courts have upheld license plate reader data collection in public spaces, yet a growing number of scholars and civil liberties advocates argue these surveillance systems may be unconstitutional. Critics assert that the scale of monitoring raises significant constitutional concerns.

As federal body responses remain muted, with an assertion that their surveillance complies with legal frameworks, lawmakers continue to demand transparency regarding the implications of such predictive measures on citizen privacy as travel escalates during holiday seasons.
