A leading Nigerian rights group is asking the U.S. government to give nearly half a billion dollars in assets frozen from a corrupt dictator to charities instead of the Nigerian government. That would help make sure the money is used to improve the lives of the people from whom it was stolen and could help unblock billions more banked by deceased Gen. Sani Abacha and held by countries reluctant to return it. (AP Photo/Jerome Delay, File)
