Anyone calling 911 and thinking they are getting anything other than a bunch of thugs that will choatically escalate what ever situation you are in, I'm sorry.
It’s always nice knowing the police in America will show up five hours after a crime has been committed, accuse you of said crime, then leave while doing nothing.
I'm not aware of this having happened anywhere. At least not with the 988 Suicide Prevention Lifeline, which I assume is the line that's being referenced.
