Chile's president condemns police violence after four weeks of unrest

President Sebastian Pinera condemns for the first time what he called abuses committed by police in dealing with four weeks of violent unrest that have rocked Chile. "There was excessive use of force. Abuses and crimes were committed, and the rights of all were not respected," the president said in a speech to the nation as it marked a month of turmoil that has left 22 people dead and more than 2,000 injured.
