So what? There were false arrests and convictions made by misuse of line-ups, DNA, eye-witnesses, photos, bloodstains, fingerprints, etc. since forever. You must also blame all those other technologies, so what do you think the police should use to find suspects? In your view, the more help police have, the worse a job they'll do. Is that actually the trend?

With all other proof you mentioned, there was always a human putting his signature.

Now that they can blame "AI" no specific officer(s) will take the blame, ever. If no one is responsible there will be many more false positives.

And false positives destroy lives

So what???

This woman lost most of her material possessions, was terrorised by "goons"... The police do this stuff regularly, as black people, immigrants, "white trash" etcetera know well. Another opportunity, presented BY AI models for more routine police oppression

As the wise singer said: "Fuck the police!"
