Man arrested for sketching in Lennon exhibition

I'm not going to translate the whole article, (if you're really that lazy, here's a google translated version), but the tl;dr is as follows:
Jan Rasmussen - A Danish citizen - was subjected to what amounts to a citizen's arrest at an exhibition of Lennon sketches in Copenhagen. He had been sketching what he saw. He was also illegally required to hand over his sketches.
All of this occurred at the behest of Abigail Esman, the American who had arranged the exhibition. The newspaper article quotes her as saying the following (translation from Danish to English is mine, I assume it was said in English to begin with): "I have nothing to apologise for. He took something that was not his. According to American law one is not allowed to copy works and we protected the law."
According to American law.
Quite apart from the fact that her action would be illegal if she had done this on US soil, it beggars belief that she felt it applied in Denmark.
Nothing will come of this. Jan Rasmussen was illegally detained and had his private property stolen by private citizens, and he will never even get an apology. Abigail Esman will not apologise and she will not respect peoples' right to self-expression. she will not learn what theft means, and she will not learn anything about either current IP legislation or sensible IP legislation (two different things).
But you should still go educate yourself about free culture. Free culture is the only kind of culture which is not out to fuck you.
