Is this actually true though? It sounds great, but where’s the data? * we need more than just the occasional anecdote to determine if this is a real issue

There are literally dozens of news stories about the wrong person being arrested for a crime they could not have committed. It's literally why cities have been banning the practice in the original news story.

Facial recognition software fails legal tests if used with large datasets. It does so b/c software does not discriminate in the same way the human mind does. For example, some facial recognition software identifies this picture of a man wearing glasses as actress Milla Jovovitch: https://images.newscientist.com/wp-content/uploads/2016/11/01160657/unknown.jpg?width=800 https://images.newscientist.com/wp-content/uploads/2016/11/0... [The New Scientist article from which the above picture is taken is "Glasses make face recognition tech think you're Milla Jovovich": https://www.newscientist.com/article/2111041-glasses-make-face-recognition-tech-think-youre-milla-jovovich/ https://www.newscientist.com/article/2111041-glasses-make-fa... ] The (PDF) original paper: https://www.cs.cmu.edu/~sbhagava/papers/face-rec-ccs16.pdf https://www.cs.cmu.edu/~sbhagava/papers/face-rec-ccs16.pdf Steven Talley was identified by the FBI as the primary suspect in two bank robberies using a facial recognition algorithm. He had an iron-clad alibi, but the police and FBI weren't convinced. In court one of the bank tellers said Talley definitely wasn't the robber. Nonetheless Talley lost his job, his wife and his family and was held in prison for months.

I found out about the facial recognition failures from he outstanding book "Hello World" by Hannah Fry. Fry tells the story of Steven Talley as part of a chapter on crime, AI and facial recognition. https://www.amazon.com/Hello-World-Being-Human-Algorithms/dp/039363499X https://www.amazon.com/Hello-World-Being-Human-Algorithms/dp... Fry's book shows how/why facial recognition software simply does not work well enough to use in police work. She provides the studies and footnotes them. As Fry says: "If you're searching for a particular criminal in digital line-up of millions...the best-case scenario is that you won't find the right person one in six times...". That is not nearly good enough for law enforcement and the courts. -from "Hello World" by Hannah Fry

The police chief in Detroit said their facial recognition system had a 4% success rate. Presumably this means that 96% of the time they were targeting someone with absolutely no relation to the actual crime. What a complete waste of time and disregard for our civil liberties. https://arstechnica.com/tech-policy/2020/06/detroit-police-chief-admits-facial-recognition-is-wrong-96-of-the-time/ https://arstechnica.com/tech-policy/2020/06/detroit-police-c...
