Sounds like suicide by cop.
I’m trying to imagine how the conversation would go:
“Officer Mack - please proceed to xyz where a woman is threatening harm to herself and others. If you get there and she attempts to harm others, you can shoot her...”
Riddle me this; if she were making threats only against others, that would be one thing. However, if she is making threats against herself, shouldn’t there be a different protocol used to subdue these individuals?
