How Putin curbs dissent using facial recognition powered by US tech

Andrey Chernyshov had just entered a Moscow metro station on his way to an anti-war protest last May, when police officers stopped him, informed him he was on a wanted list and, without further explanation, escorted him to a police office inside the station.

There officers told the 51-year-old bank employee that the metro's facial recognition system had flagged him for detention because of his political activism. A little over a week earlier Chernyshov stood alone by a fountain in central Moscow's Pushkin Square and held up a home-made poster that said "Peace to Ukraine," "No War" and "Freedom for Russia."
