I don't know how the law works in Holland, but if it's anything like the UK and Australia, you have to actually take them to court personally. It's pretty much getting the same the world over, that the police force isn't there to protect and serve, but to make money.
Can you show them something in writhing which says that this is their area to deal with? Having said that, maybe that's how they deal with it. Or maybe you could talk to the press about it. 😉
