tl;dr: Police across the US are increasingly using automated license plate readers (ALPRs) and AI tools from vendors like Flock Safety and Axon to pull over drivers based on "suspicious" travel patterns, even without probable cause. The ACLU highlighted cases including a woman stopped by an FBI agent who showed her a heat map of her movements, and a Texas jury recently sided with a driver who sued over an "unconstitutional traffic stop scheme" enabled by the technology. Backlash is growing, with agencies like the LAPD suspending or ending their Flock contracts.
