In the Netherlands, even wearing an outfit that could be mistaken for a police uniform is illegal.

Collection agencies and such also just love threatening with eviction or seizing of property to pay your debt. Which has been made kinda illegal a few years ago.

A long time ago, my late FIL(he was a fiscal advisor and had his own video rental business in the 90's) told me that unless the collection agents are accompanied by actual police and bear a letter that starts with "in the name of the king", they can't do anything.

And, no, its not like the actual king issues those letters, its legalese wording that means its a court order.
