This is a tricky question and the answer is neither "yes" nor "no." In the vast majority of cases, no police (or other authority) involvement is required and in the cases where emergency help is needed, suicide hotline staff will make every attempt to gain permission to send them. The goal of a suicide hotline is to help you with your personal crisis and no one-size-fits-all solution is possible.
That being said, if you are actively suicidal and threatening to imminently hurt yourself, it is possible that emergency personnel may be called without your permission. While no one likes that scenario, it truly is the best, lifesaving thing an operator can do in a small number of cases."

There are numerous reports of police showing up to suicide calls and shooting someone.[1][2][3][4][5] There's certainly a discussion to be had here about whether the shootings are self defense, but Taylor_OD's speculation is certainly not "without evidence".

The person was shot after attacking the cops. You make it sound like they just shot these people for fun.
The person? There's five different articles with five different people.

Did you actually bother reading my post? I brought up the possibility that the shootings were self-defense--nowhere did I blame the cops.
