Capt Steve,
The more I read this thread and think about what happened, the more PO'd I get. Here's an idea:
The law varies from state to state, but I am sure you can check to see how it is done in Arizona. Google "Arizona mental health commitment law," and see what you find.
In many states all it takes for a 72-hour mental health hold and evaluation is the signature of two adults on a petition to the local court. In some places, it has to be one physician, of any specialty. In others, it takes the signatures of two psychiatrists. I am hoping that in Arizona all it takes are the statements of two adults. That's you and any one of your golf buddies.
If you go this route, check with an attorney first to see if you are opening yourself to any civil liability. It seems to me that you and your friends have reasonable grounds to wonder about this woman's sanity, so you're doing this can't be considered vindictive or abuse of process. I do not think that is the case; then again, I am not a lawyer, and I do not live in Arizona.
If this works, once the magistrate issues the order for her to be detained and transported to an in-patient mental health facility for a mandatory 72-hour evaluation, the local LE agencies will be required by the judge to go pick her up. The LEOs will know what happened and so they will go prepared and ready. She will then have 72 hours on an inpatient unit to prove that she is not whacko. If she is as unstable as she sounds, she will fail, big time. The great thing about inpatient psychiatric units is that there in no limit on how long they can hold someone they consider to be a imminent threat to themselves or others. If you are fortunate, she will be there for much longer than 3 days, you will have the satisfaction of having removed a dangerous person from the streets (or fairways), and the right to tell the LEOs who failed you so miserably "see, toldja so!."
I can understand if you don't want to go this route, but I am trying to come up with a way to take this woman off the streets regardless of what your local LE agency does, or in this case, doesn't do.
