Over here (Left coast USA) the media not only can but HAS changed perceptions over entire watersheds. I've watched in disbelief the drip, drip, drip propaganda of big city media inculcate perfectly sane family members into registered left wingers rabid to abolish guns and knives.
Correct me if I'm wrong, but from what I see of the EU media they are leading the world in veering left. I agree with others above who advise working around Dutch customs, and I underscore doing it like a mole tunneling in soft dirt. IMHO going public may foment triune risks, not only to import knives but to Marcel's existing collection as well--an irate/vindictive state, opportunistic thieves, and possibly the public itself, viewing Marcel a public menace with all those weapons of mass destruction.
