When you tell someone to basically go away in the interest of their own safety and they tell you to f-off, your demeanor tends to change, don't you think ? Now, I'm not saying these guys were offering to escort these "ladies" across the street, but the story does say that the chief says she appears to have some culpability in her own injury.
That's the centerpiece of this story. I'd expect the demeanor displayed by the cop from someone in the bar, but not from the police outside the bar. The fact is that the cops didn't close the bar. That's what you do in sits. like this. Just announce the bars closed folks and that's it. You tell the barkeep and the bouncer to clear the place, lock the doors and tell eveyone go home.
You don't arbitrarily pick out at random folks waiting in line and tell them to go home w/o closing the bar. Then get irritated if they say they don't want to. That's like picking out folks standing in line for a sale at the mall and telling them to go home while the rest get to shop. They won't care if there was a recent struggle over some item and the cop claims it's for their own safety.
This cop got into a personel dispute with 2 women patrons that were being served by the establishment and had a legal right to be there. The "safety" claim is bogus. The cop couldn't handle the sit, blew his top, went after the woman and broke her arm. IOWs he turned it into something personel. Nothing admirable, or professional in that.
Who knows what the chief thinks. I suspect he might have used the f word when he heard about this, or during a quiz of the officers involved though.
