AI metal detector in subways faces potential legal challenges after NYC rolls device out

New York City has officially deployed a metal detector powered by artificial intelligence in a bid to catch people carrying guns onto the subway system — and the program is already facing the threat of litigation by groups concerned by the implications for New Yorkers’ civil liberties.

Mayor Eric Adams on July 26 announced the long-promised rollout of gun detection scanners manufactured by Evolv Technology for a 30-day pilot in the subway system. Not everyone will be required to go through the scanner — Hizzoner said it “could be every fifth, 10th, or 20th person” randomly selected for scrutiny — but those selected will have to go through the scanner if they want to enter the subway system where the tech is deployed.
