London scanned 500,000 commuter faces, got one false alarm, zero arrests—and is expanding anyway
“Half a million faces. One innocent person. Zero criminals. More cameras incoming.”
The Story
A six-month live facial-recognition trial at London railway stations scanned more than half a million faces, cost about £320,000, used nearly 100 police hours, and produced one alert—which was wrong. No arrests came from LFR matches. The force still extended the trial onto the Tube, and the Met is moving toward fixed cameras in the West End and pedestrianised Oxford Street.
Why It Matters
A city built a panopticon that doesn’t even catch anyone, then treated failure as a reason to scale. Institutions plus absurdist surveillance, not a Flock rerun.
