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

"Well now we know : 12.5% efficient."

Nope, not even close - https://en.wikipedia.org/wiki/Base_rate_fallacy

These systems have already been shown to be AT LEAST as likely to MISS a wanted person as to flag innocents as wanted - but because the Met don't _measure_ a false negative rate the real figures are utterly uncalculable.

A system which flags a middle aged, short, fat black woman as matching a wanted, tall slim 19yo black male - whilst failing to go off on 20 wanted white criminals isn't worth the cost of the cameras unless your agenda is to perpetuate the ongoing culture of institutional racism.
