Are you really sure? That would have been interfering with the criminal justice system of the Netherlands. This would, most likely, have caused a terrible scandal with strong international repercussions and huge damage to many international relationships, I bet.
Furthermore, I recently read an article on the subject of Nazi devotionalia. It is legal to own them and to have them in your house, if you have inherited them from your Family.
Still, it is discouraged to deal with them in a business-like manner (though in fact, prosecutors would have a very hard time ascertaining the provenance of any given item from the NS era). Nonetheless, there was a huge auction of NS paraphernalia in 2019, in Munich, which was widely criticized.
I didn’t think I could find such an old item that I only saw a tiny mention of, but here is the guy, from the SPLC.
I couldn’t understand why there was no uproar about an American being arrested for this and in this way.
“In 1995, Lauck was arrested in Denmark on international warrants for disseminating illegal propaganda in Germany. He was staying at the time with Jonni Hansen, chairman of the neo-Nazi Danish National Socialist Movement. A few days after his arrest, German police raided the homes of 80 Lauck followers, many of them teenagers, and seized weapons, ammunition and illegal literature. Extradited to Germany from Denmark, Lauck was tried and sentenced to a maximum four years in prison for his activities. By the time he emerged from prison in March 1999, Internet-based propaganda had supplanted him, rendering his propaganda work, particularly in terms of smuggling hate materials into Europe, vastly less important.”

By the way, when I said “nabbed him” I knew it was with the consent of the Dutch and I didn’t mean like they kidnapped him and smuggled him out, I worded it badly/lazily.
