FILE - In this April 9, 1988, file photo, Los Angeles police officers search one of seven people arrested for selling narcotics in the south-central area of Los Angeles, as more than 1,000 police officers raided gang strongholds to attack on drug dealing and street violence in the nation's second largest city. In 1971, President Richard Nixon declared a war on drugs. It is questionable whether anyone won the war. Who suffered the worst losses is clearer: Black Americans, their families and their communities. (AP Photo/Douglas C. Pizac, File)
