During the Vietnam War, some U.S. soldiers collected the skulls of Vietnamese as war trophies. They often painted them or found utilitarian uses for them, for instance as ashtrays. Six of these skulls were confiscated by the Customs Department when U.S. soldiers tried to bring them back to the States with them. Since then, the skulls have remained for years at the Walter Reed Army Medical Center in Washington. Should the U.S. return these skulls to Vietnam? The New York Times has more about these Vietnamese skulls.
