In reality there is the decade old problem that the Dutch justice system cannot handle the amount of criminals. Not enough judges and money for that.
Partly because of this it has become very hard in the Netherlands to even file a police report for light to medium weight crimes committed to you. Police simply send you away if a crime is not heavy enough in their opinion. Criminals walk free on the street, and when they are caught they most often are back on the street the same day, unless it is a real serious crime of course.
At some point they even decided not to file a police report below 3Kg of cocaine smuggling from the Dutch Antilles. Why? There were just too many doing it and the justice system couldn't handle it..
The Netherlands in reality has a very high crime rate, but the government found smart ways to conceal that.
