"A few years back, the promoters of "Bodies…The Exhibition" had a problem. The traveling science-museum show, in which preserved corpses stripped of their skin are used to display the human body's internal organs, needed a supply of cadavers in good condition from healthy people (who just happened to be dead). By a fortunate coincidence, the Chinese Bureau of Police had a generous supply of that very item that it was looking to unload, and so a deal was struck. The exhibit has traveled the country since 2005, increasingly hounded by questions about the origins of its bodies. Now, in a settlement with New York state, the promoters have admitted that they are not sure whether their cadavers were among the thousands of prisoners that China executes every year (whose remains, when not preserved whole, are often harvested for organ transplants by the thrifty Chinese government). Anyone who saw the exhibit in New York and objects to the Chinese connection can get a refund; future visitors will be told of the bodies' uncertain origins. And perhaps museums will learn to be just as careful about the provenance of their human exhibits as they are with works of art."

Not sure? Not sure!?!
