I think better than having regular LE officers put on the spot in such situations would be having access to a professional to review the concern-causing evidence and also be present to speak with the subject.
A nice little chat instead of bothering to check any evidence surrounding someone who has been under life-long psychological care, has started posting murderous videos, and has family and friends vouching for concern just doesn’t cut it IMO.
I agree, but LE officers are handicapped by the system they work for. Sometimes all they can do is talk to the person. That is why, at least here in VA, the parents, or their therapist can call the magistrate directly, and swear out an ECO for that person. Once it is issued, police pick him up no matter what he says. Tough spot to be in...
