Okay.
I spoke with Dr. Alan Drummond, who's an emergency room doctor. He said that when there's imminent danger it's easy for him to respond, in particular around suicide, but when there's a question about the potential, he has concerns.
I have heard this from women's organizations when there has been coercive control, for example, and someone is threatening to shoot a companion animal, like a dog. The woman hasn't been shot and hasn't been punched, but there is coercive control. This is much more difficult, and I would expect it to be more difficult for police officers to respond to that as well.
