I was under the impression that the Smithsonian had a policy of not displaying human remains, especially after NAGPRA was passed. I wonder if that has anything to do with most of the skulls being white, that they're more modern donations instead of from the historic collection. Not that explains their other fail like in the slave display, but I've found their international/interracial displays to always be pretty crap. My BF and I went to their Korea exhibit not too long after it opened because he studies Korea professionally. The overall impression that I got from the exhibit was that Koreans made a lot of fancy pottery and gave ducks to people as wedding presents. Very little else. It was extremely disappointing, and I have similar feelings about a lot of their new exhibits over the last five years.
