It is pseudo because it does none of the things you said with none of the accuracy you propose.

What it does well, is tell you whether the specific picture of a person you feed it looks roughly similar to other pictures of other people that belong to a certain category.

All of it's predictive power comes from the fact that the datasets they are trained on are completely imbalanced and that society has inherent biases, so it just picks up on that and magnify it.

I can guarantee you that a picture of a white male CEO in a suit and a picture of a black young adult in everyday clothing will score extremely differently on the model no matter what their personal criminal proclivity is.

Human (cops) do the same thing: they are used to a certain population being more at risk of criminal activities and thus they will control anyone from that population much more (e.g. stop and frisk in NYC).

This is illegal in most places. We are doing the same thing all over again, except now, we can do that through a blackblox brand "AI" on it, call it science and legalize it again.
