How do you check it out without violating rights? Believe me, I’m all for it, but if he/she has done nothing wrong except be weird, what can law enforcement do?
Indiana has statutes that allow for voluntary and involuntary civil commitment...

That is a issue. Like with threats, can’t do anything until they do something. That something is what happened at fed ex most of the time. You hear of women calling and saying they are afraid and been threatened by husband or neighbors but the cops can’t do anything until they do what they threatened. By then it’s to late.
