Ninth Ward area resident Robert Richardson holds a poster reading 'Stop Ethnic Cleansing' during a memorial ceremony in New Orleans August 27, 2006, nearly a year after Hurricane Katrina struck. Some critics have charged the government's slow response to the hurricane was due to racism because the areas hit were largely poor and black, an accusation that administration officials have strongly denied.
