@Walter Hinteler,
Quote:What I really don't understand:
a) when you shout something like "You are dead", you have to undergo an involuntary examination?
b) this examination can be ordered by police officers?
That's really just personal interest - I couldn't find the related laws on the internet - because I've been involved here with this quite often. And since it's extremely different [a physician has to examine you at first (mental health related), the local department of public security (re danger to other and/or yourself) has to sign that examination order; then a judge has to decide within 48 hours if you stay in a psychiatric hospital) I'm asking here.
A discussion about the issue of gun control was going on at this forum which was being taped for broadcast on ABC this morning. Mr Fuller (one of the victims of last week's shooting) was in the audience and he became enraged at Mr Humphries (a spokesman for the local Tea Party) who was also in the audience, after Mr Humphries stood up and said that he felt that any discussion of gun control should be delayed for a while. Mr Fuller apparently then photographed Mr Humphries with his cell phone camera and then shouted at him, "You're dead". He also was reportedly yelling and saying things like. "You're all whores". There appeared to be tight security at this event, and the police present arrested Mr. Fuller for disorderly conduct and threatening as the forum was ending.
So, to answer your first question--No, just because you threaten someone does not mean you have to undergo an involuntary psychiatric evaluation.
Threatening someone, as Fuller did, is a misdemeanor criminal charge, and that's why he was arrested. Based on Mr Fuller's behavior after his arrest, the police felt that a psychiatric evaluation was warranted, so instead of transporting him directly to jail, they took him to a hospital to be seen by a psychiatrist.
To answer your second question--The evaluation was not ordered by the police. It was requested by the police because of the way Mr Fuller was behaving. So, a psychiatrist in the ER of the hospital (or whatever mental health facility they took Mr Fuller to) then performed a mental status examination and apparently felt that Mr Fuller did require a 72 hour hold for further psychiatric evaluation--and this was an involuntary hold--to determine whether Mr Fuller constituted an immediate threat to self or others, due to a mental disorder, and whether he required psychiatric treatment. Mr Fuller cannot be held beyond the 72 hours without a court order and statements from the evaluating mental health professionals that he requires a longer period of inpatient psychiatric treatment. They can also choose to release him at any time before the 72 hours are up.
I can't find the specific procedural codes for Arizona, but here is a general discussion about involuntary psychiatric holds. The procedures are fairly similar from place to place.
