Uhm, in Germany it's completely normal for police to assist in situations of mental health and instead of shooting them they talk to them, or, as a last resort, restrain people and bring them back to a care facility, unharmed.
Police receive proper 3 year training and most of them even have a required university degree.
During an interview for an office job without contact to clients they told me I should do something about my hair because they are a conservative, family owned company and wanted to represent this.
I simply had long, clean hair in a pony tail. I walked out of there, didn't want that job and am proud of that.
