Something that Prison Officers are taught in training.Not necessarily MOE police, but BETTER policing. Not taking hte knee. Not dancing with da yoof or attending Gay Pride - you know, getting pally with the populace. The difference being being pals and being friendly. When the populace are getting raucous, it is harder to police them if they feel that you are their pal and that you will cut them some slack. This is the case of giving a finger, losing an arm.
From what I remember, the Police chiefs stated that the crime levels were dropping, so the Home Office minister/s of the day said "save some money". This is a part of the reasoning behind the reduction in police numbers.
"Be friendly but never be their friend".
