Points and comments are a snapshot, not live.

A UK trial scanning 500,000 faces at stations led to no arrests and one false positive.

A six-month trial of live facial recognition (LFR) cameras in London railway stations cost £320,786, used nearly 100 police hours, and scanned over 500,000 faces between February and July 2026. It produced one false positive alert and zero arrests. The British Transport Police later extended the trial four months to include Underground stations, reporting three confirmed alerts of people complying with court orders. The Metropolitan police plans to install fixed LFR cameras in the West End, and London mayor Sadiq Khan confirmed the technology will be used on pedestrianized Oxford Street.

What commenters are saying

Commenters broadly condemned the trial as security theater, with many noting the poor cost-effectiveness and lack of arrests. Some argued the definition of criminal could expand to justify surveillance, while others pointed to successful UK trials elsewhere making 103 arrests. A few questioned whether falling crime rates were due to extra officers rather than LFR. One commenter noted 500,000 scans over six months seems low for London stations, suggesting the system was rarely active or targeting a small watchlist.
