Look dude, I have had some experience in such situations with relatives. They all said no initially, but we achieved what needed to be done without calling the cops.
I do have power of attorney for people in my immediate family, because that is the logical, smart, and well prepared thing to do.
The cops can’t do anything that the family can’t, cops are more likely to shoot the person, and cops are not likely to be as persuasive as a trusted family member.
I do agree that using medical personnel trained to deal with such individuals is better than the current system.
Calling the cops turns a bad situation into a potentially deadly situation. I wouldn’t do it. Ymmv.
