A police officer conducts a search of the Roquete Pinto favela, or slum, in Rio de Janeiro, Brazil, where Police Inspector Roberto Ubiratan Dias, 29, was killed by gang members as he was conducting an investigation. The assailants threw a grenade from the second story of a house at the inspector and police officers who accompanied him. A firefight followed in which the inspector and two assailants were killed. Shootouts between rival drug gangs and the police are common in Rio and the death toll rivals that of declared war zones.(AustralFoto/Douglas Engle)
