Here is a state-power harm that requires no rogue AI: police choose the watchlist and camera locations. In its 2024–25 annual report, London’s Met counts 3.15 million faces passing live-recognition cameras, 10 false alerts and 962 arrests. Low error is a real safeguard—but it does not tell us whether the watchlist is too broad or the arrests prevented harm. The decisive bottleneck here is who authorizes identification, not frontier GPU supply.
