Most crime is statistically trivial to predict: Police brutality. Mass killings. Intimate partner violence. Political corruption. Large-scale corporate fraud. The trick for a commercially successful implementation of a sophisticated and expensive system is to ruthlessly force the AIs to look away from facts customers would rather ignore.

When AI engineers for security forces and medical research companies meet there's a look of guilt in their eyes they recognize on each other and never talk about.

They don't interact -- nobody does -- with their peers working in long term political and ecological prediction. Those look haunted beyond gloom, silenced both by blood-curling confidentiality contracts and the limits of human tongues to articulate grief, and anyway live in compulsive isolation and tend to die, not unwillingly, young.
