Yes Robert I won't defend the Brits. But I also remember that the Dutch had a terrible reputation too for hooliganism

I'm sure you remember that. In passing, I used to visit Ghent once or twice a month for many years - and I can tell you, that the Sunday influx of the Dutch hoolies was much dreaded.
I don't defend the English sub-culture. But the French seem to have brought this to a fine and persistent art

Do you have any answer to my question ? WHAT can the Police do ? Nice evening . . . .
