Police are reportedly pulling motorists over because AI algorithms deem their driving patterns 'suspicious'

The American Civil Liberties Union has released a report highlighting the growing use of artificial intelligence by law enforcement to justify pulling over drivers. According to Jay Stanley, a senior policy analyst with the ACLU Speech, Privacy, and Technology Project, police are employing AI algorithms and automated license plate reader surveillance to flag motorists with suspicious travel patterns, even in the absence of evidence of wrongdoing.

Stanley expressed concerns that this approach could lead to an increase in pretextual stops, where officers target individuals based on predictions made by AI algorithms. This could result in more innocent people being subjected to police encounters due to the algorithms' tendency to flag a larger number of innocent individuals compared to actual offenders.

The report outlines several incidents where individuals claim they were pulled over because a surveillance system deemed their movements suspicious. One such case involved a woman who was stopped during a cross-country road trip after an officer used a surveillance system that had flagged her travel patterns as suspicious, after accessing Automated License Plate Reader data on her movements.

ALPRs, which photograph passing vehicles and record their registration numbers, locations, and timestamps, allow law enforcement to track a vehicle's travel history, routes, and frequency of visits to specific locations. When paired with AI systems trained to identify suspicious patterns, law enforcement can quickly analyze vast amounts of data and generate alerts about potential suspects.

Some officers have been accused of concealing the true reason for a stop, relying on the AI's predictions to justify the encounter. The ACLU report comes amid growing concerns over the impact of mass surveillance camera networks, including issues of privacy, abuse, and limited regulation. Several officers have faced firing for abusing surveillance systems like Flock.

The use of ALPRs has expanded significantly, with a network of over 335,000 Flock ALPR cameras now active across the United States. AI has enabled these systems to analyze large collections of vehicle movements and generate new suspects based on behavioral patterns, marketing them as crime-prevention tools.
