If I were in the USA? I'd blow her fucking brains out second one.
How would I react if I was a cop in my country? I don't know I studied Mechanical Engineering because I wanted to get away from my father's field.
I do have something very few people have in my country, a legally owned self defense gun but I never took it out of it's box because I don't live in the US and we deal differently with mental health. If I had my gun with me I'd probably shoot her in the torso because I'm not a fucking main character in an action movie headshotting people left and right.
And no, I didn't see de-escalation reports because he was the I don't know the english term, he basically was chief so he was responsible for everything that those under him did. That meant he went to the worst of the worst so instead of 2 people slapped eachother it was mostly "guy drove his motorcycle under a truck and got decapitated" or "2 gypsy clans butchered each other on the streets" or "guy did business with the wrong guys and didn't pay them back so his maid, wife and daughter got their heads bashed in with hammers".
I'm sorry but I'd rather not potentially give my life away in a situation where I can legally be 100% safe.
