Just looks like a case of stupid Policemen to me, they were very very lucky it wasn’t a mastiff pitbull cross, or a rottweiler as then it would have been much worse.
Hopefully they all get a serious bollocking about the huge mess.
What amazes me was the reaction of the copper getting bitten. If it had been me i’d imagine i’d be kicking and swinging anything I could at it whilst it was on me.
I bet you wouldn’t have been, in real life it isn’t like TV as dog bites can penetrate sheet steel, so whilst you think you could cope with the pain of your bones starting to creak and fracture and your flesh tearing I bet you would be acting like the bloke in the clip and not as you imagine.
I know people in the forces who use dogs to clear houses in a certain dusty hot place, and they have all said that a single dog can clear a house of armed (very proficient) men in minutes and these people are hardened fighters with lots of weapons and experience.
