a story of patriotism...

But, kicking his arse (8 police)? Come on man, was resisting the removal from the building? I suspect not.

Well we only have the OP to go on and thats already been demonstrated as rather light on actual accurate factual content. But lets work on it.

Well its claimed in the OP that he was waving a stick and disrupting a meeting. How many police would you consider appropriate considering of course that Darkfish said a large number had gone to protest?
Resisting removal? He would have been told to shut up or leave , since he did neither voluntarily what were the chances of him just leaving when the police asked?
Now if he had been protesting in a country not quite as relaxed as the Netherlands then perhaps Darkfish might have been treating us to a video of his dad getting tazered or gassed or just beaten with a nightstick.
