LONDON (AP) — When British police used facial recognition cameras to monitor crowds arriving for a soccer match in Wales, some fans protested by covering their faces. In a sign of the technology’s divisiveness, even the head of a neighboring police force said he opposed it.

The South Wales police deployed vans equipped with the technology outside Cardiff stadium this week as part of a long-running trial in which officers scanned people in real time and detained anyone blacklisted from attending for past misbehavior. Rights activists and team supporters staged a protest before the game between Cardiff City and Swansea City, wearing masks, balaclavas or scarves around their faces.
