NEW YORK (AP) — New York City is turning to AI-powered scanners in a new bid to keep guns out of its subway system, but the pilot program launched Friday is already being met with skepticism from riders and the threat of a lawsuit from civil liberties advocates who say the searches are unconstitutional.

The Evolv scanner — a sleek-looking weapons detector using artificial intelligence to search riders for guns and knives — was on display at a lower Manhattan subway station where Mayor Eric Adams announced the 30-day trial.
