This story is really alarming because as described, the police ran a face recognition tool based on a frame of grainy security footage and got a positive hit. Does this tool give any indication of a confidence value? Does it return a list (sorted by confidence) of possible suspects, or any other kind of feedback that would indicate even to a layperson how much uncertainty there is?

The issue of face recognition algorithms performing worse on dark faces is a major problem. But the other side of it is: would police be more hesitant to act on such fuzzy evidence if the top match appeared to be a middle-class Caucasian (i.e. someone who is more likely to take legal recourse)?

This needs to be coupled with the truth that people (police) without diverse racial exposure are terrible at identifying people outside of their ethnicity. In the photo/text article they show the top of the "Investigative Lead Report" as an image. You mean to say that every cop who saw the two images side by side did not stop and say "hey, these are not the same person!" They did not, and that's because their own brains' could not see the difference.

This is a major reason police forces need to be ethnically diverse. Just that enables those members of the force who never grew up or spent time outside their ethnicity can learn to tell a diverse range of similar but different people outside their ethnicity apart.
