I think that for me that most important issue here is how was the artifact originally obtained. Artifacts stolen outright from various cultures around the world should be returned if they want them, plain and simple.
Andrew, i am sorry to go off topic for a moment and i don't mean to prolong this discussion. I just hate rumor and inuendo. I don't really know how i feel about this body art guy, but i see no evidence that he is using the bodies of Chinese prisoners for his purposes. They are donated by their owners prior to death as far as i can tell and the "artists" best friend is apparently among them.
But there does seem to be some scientific merit at work here.
