Public confidence?
There IS none. AI is a load of bollocks in general, deep learning & machine learning algos are a bad joke, & facial recog is just another way for the Powers That Be to arrest you first & claim a reason for having done so after the fact.
The whole thing is a right clusterfuck that should be scrapped, restarted from scratch, & done correctly from the get-go.
Nobody should be allowed to use it until the false posative rate is below 10% at the worst of times & under 1% at the best. Those it flags should then be gone over with a judicial fine toothed comb to verify/reject if the person flagged is the person sought. "You're looking for a white male about 20 years of age, 1.98 meters tall, 80 kilos in weight, with a tattoo of a dog on his cheek. THIS is a 75 year old black man who's all of 1.25 meters tall, 50 kilos, & has no facial tattoos at all. On what planet does this make a match? Get out of my office before I have you arrested for being a fucking idiot."
*Cough*
Bin it, scrap it, start over.
