Lots of police departments don’t bother to screen for psychosis or sociopathy.
It’s a trade whose toolbox is filled almost entirely with violence, threats, fear, and coercion. It’s the one career society sanctions to intimidate, harass, cite, detain, and kill it’s own. The institution itself seeks out, nurtures, and promotes those who can plausibly create the most rubble in the lives of their fellow citizens.
…their fellow citizens.
I’d say the job of “peace” officer screens for psychosis and sociopathy quite well.
