If you're wondering how Brit cops' live suspect-hunting facial-recog is going, it's cruising at 88% false positives  The Register reports. 

The latest figures from the Met Police's deployment of facial-recognition cameras in the heart of London show the technology is pretty inaccurate.

On February 27, for instance, the cameras scanned an estimated 8,600 faces in Oxford Circus, checking them against a watchlist of 7,292 people. The AI tech flagged eight as being possible matches; seven turned out to be false positives, five of whom were actually stopped by the cops and two dismissed as obvious errors. The remaining person turned out to be a true positive, and was intercepted by the British plod.

That's a false-positive rate of 87.5 per cent of those flagged up by the software. About two weeks earlier, in Stratford, the AI matched none of the 4,600 faces it scanned against its watchlist. On another day, the system broke, and no one was scanned.
