Trial of live facial recognition in London stations leads to a false positive and no arrests
A six-month British Transport Police trial of live facial recognition at busy London railway stations scanned over half a million faces, cost more than £320,000, and consumed nearly 100 officer hours. A freedom of information request revealed the effort produced one alert — which was a false positive — and zero arrests.
Why this matters: Half a million people had their faces scanned without any say in it. The return on that was one wrong hit and nothing else. That is the part worth sitting with. Supporters of facial recognition usually argue the scale of surveillance is justified by results. There were no results here. The cost was real — public money, officer time, and the quiet normalization of scanning everyone who walks through a train station. When a program like this fails this visibly, the question is not whether to tweak the technology. It is whether this kind of mass scanning should run at all before it actually works.
