Man of Honour
I saw and heard nothing on that video which should have prompted the verbal abuse and physical restraint used by the Officers.
You saw exactly what the filmer wanted you to see.
Notice how there was a large edit in time from just arriving, to the close up of the Police car ?
How do you know he hadn't been loitering there for hours, asked numerous times to move on and had been swearing at the police - You don't
Then there's the lost picture but sound works fine part, where he can say anything he wants without any proof ?
Without a picture he can say 'put down that flamethrower and stop shooting me with lasers' and you rely on his word only.
He was arrested using reasonable force for someone who was far from compliant and a potential threat to the safety of the police station and personel
