The French police still behave like proper policemen with suspects regularly 'banging their head getting the back of the transit'. They also have the total support of the greater part of the population.
Here's a report from Calais last year:-

Whereas in this country there would probably have been an expensive enquiry, accusations of institutional racism and race awareness training for 'tout le Plod', over there no-one actually gives a toss and if someone gets tear-gassed or banged over the head the general consensus is that perhaps they shouldn't have been there in the first place.
They have a Police Force (the clue's in the word 'force') dealing with crime, we now have a Police 'Service' of uniformed social workers dealing with people with 'challenging behaviour' caused by 'chaotic lifestyles' making 'poor choices'.
I prefer the French system.
