According to Hardi N., prime suspect in the terrorism trial of a group of Arnhem jihadists, it was an AIVD security service infiltrator who gave him the idea for an attack in the Netherlands. So that would be incitement, but if so, can it ever be proven? N. was sentenced to 18 years in prison.

The police dossier of the investigation into the Arnhem jihadists who wanted to carry out an attack in the Netherlands is impressively thick. Extensive accounts are given of how a police infiltrator ambushed the men. How he gained their trust and learned that they wanted to commit a massacre at a festival with Kalashnikovs and bomb vests.
