Police use water cannons Friday, March 18, to clear the main avenue of Sao Paulo, Brazil, where people were protesting Brazilian President Dilma Rousseff and her ministerial appointment of former President Luiz Inacio Lula da Silva. Rousseff named Lula da Silva as her chief of staff, and her critics say it is an attempt to shield him from a corruption investigation.
