This doesn't look very good to me:
What was the huge hurry in getting this person out of the car?
Is "do what I say - or I'll use what's basically an instrument of torture on you" acceptable from police?
Despite the request/expectation of the judge who allowed this to be released, the article by NZ Herald doesn't give context which seems important to me, was he going to flee and become a danger to anybody else, could the car have been immobilised (ie the cops presumably arrived in cars, and could have blocked the car in).
I have no idea / haven't read about the individual apart from the apparent fact that he'd assaulted his elderly father which clearly isn't a very nice thing to do (understatement) and for which it's hard to imagine anybody would have a lot sympathy even though he died in moments after this video was shot. This looks like brutal police violence - or at best hysterical and inappropriate overreaction to me.
Please assure me I'm wrong - defend what looks indefensible.
