Someone should let these people know that nobody gets put in jail based on the facial recognition’s decision, so their “concerns” are impossible. Not only that, but if anything, it’s less likely to find darker skin tones at all, so it will favor minorities, not hurt them.
It’s a shortcut for manually digging through databases to identify people. Any identification is followed up with investigation, just as it would be if a human matched it. No decision is made by the machine.
So, no, it’s not racist at all.
