The vast majority, if not all cases of police brutality in Britain (not counting Northern Ireland) have been committed against non-armed - not criminal citizens, the overwhelming number of them have been against protesters.
There is no excuse for police brutality of any form - none, though I am not surprised there are those who appease it; nor am I surprised who they are (you could have written their script in advance).
last year there were over 3,000 police officers being inveestigated for alleged police brutality - all were still on the beat (SORRY - CAN'T CLICKIE IT)
