Earlier quoted context omitted.
Also a hotspot for drugs trafficking, yet with a pristine official record of corruption, ranking as one of the ten least corrupt countries in the world. These seem incongruous, somehow.
Not incongruous, I think. By basically legalising drugs, prostitution, and similar victimless peccadillos (and focusing on treatment and support instead), you destroy the mob's business model, reduce opportunity for corruption, and allow cops to concentrate on real crime.
There are drug labs basically everywhere in the countryside.
All global organized crime syndicates have a local presence.
With regards to prostitution, human trafficking has actually increased and prostitutes get imported and pimped out. Half the business is legal so the police have even less incentive to care, especially if the victim and the pimp are both foreign. Basically free tax money and no harm (to ethnic Dutch people).
There's also lots of arms trafficking.
