London's top cop dismisses 'highly inaccurate or ill informed' facial-recognition critics, possibly ironically

@JetSetJim

So you are saying that London's cops have this database of faces that they are using for facial recognition, enhanced questioning, ID checks, maybe frisking, and possible arrest. This database of faces contains DUPLICATES of the same face because this supposedly accurate system can't tell the difference between a mug shot of bad guy X after he got picked up for whatever offense from a frontal CCTV picture of bad guy X breaking into a car or from a side CCTV image of bad guy X robbing a liquor store?? So this advanced facial recognition system can't even affirm identity in its own database to the point that it can de-duplicate its own data and affirm that it has three images of the same guy in its database, and settle on the one that best identifies this hypothetical perp?

I think that right there, you just justified scrapping this system based on inaccurate identification and a demonstrated lack of truly being able to recognize an actual bad guy, vs. stopping a law-abiding person who just happens to look a little like one of these multiple images of the same suspect floating around in the database.
