Re: Trust the police?
I have known quite a few members of The Thin Blue Line and they, like any other group, have their share of good and bad people. But as Peter2 noted, by the time the boys and girls in blue turn up, things have normally gone bad anyway so you're not seeing them at their nicest.
But all that aside, don't AI systems learn by experience? Which means if they can recognise white males more accurately than other facial types, they must have most experience of looking at white male faces? Which means they must have been shown more white male faces?
But then, white (straight) males are the only group not to have a "Rights" group lobbying for them, so is this really surprising?
