These "therapists" (adult babysitters) need to be held accountable. Anybody exhibiting certain psychological profiles should be referred for civil commitment and locked up.
The "mental health professionals" have a pretty good idea what their patients are thinking and what they are capable of.
The short term solution should be: survivors and family members of the victims of these murdering psychos should now sue their "therapists" out of existence, and they should never be allowed to practice their "art" again.
And not just psych profiles - how about habits of threats to do bodily harm or kill others, and violent behavior???
That's part of the protocol. It is for lawyers too, FWIW.
The flip side is that to the extent the public is aware these professions will rat out the customers, the customers resist assistance from the professions.
