Sane people don’t do these deeds. Wife works with the worst of them in the school. She can see their eyes are empty. They have no feeling. True sociopaths and psychopaths. She can get them admitted only for a few days and only if they are a threat to themselves. They need to be institutionalized and heavily medicated.
We closed most of those facilities in the 80s and 90s. Let the cops deal with them. And if they’re bad enough, the prisons. Well that model clearly isn’t working.
