It absolutely is.
"I felt threatened" isn't carte blanche to attack someone, mate.
That's as good a case study as any for how police shouldn't escalate.
[Edit] Here's an example;
Tola Munro has a distinguished career tackling violence against women and girls.
www.bbc.co.uk
- Ms Jones said he has police "experience and training" to "rise above provocation" and must take "full responsibility for his conduct".
In other words, he can't slap people around because he says he felt threatened by words.
Indeed, and that happened directly as a consequence of that officer/dog attack. The guy tries to help release the dog bite.
No correlation whatsoever. Shouty words>walking away is clearly not in the ball park of viciously attacking multiple police.
If they started wading punches in/breaking noses/were attacking that dog handler, then absolutely - all bets are off and have the dog go for the throat.
