Demonstrators clash with the military police in front of the Legislative Assembly in Sao Paulo on August 2, 2013 as they demand the resignation of Rio de Janeiro's Governor Sergio Cabral, accused of corruption and arrogance, and Sao Paulo Governor Geraldo Alckmin, as well as the demilitarization of the military police and against the disappearance of 42-year-old construction worker Amarildo de Souza who has been missing for two weeks after he was picked up by police at Rio de Janeiro's Rocinha shantytown. Hundreds of youths marched in Rio and Sao Paulo Thursday as police kept a close watch.   AFP PHOTO / Miguel SCHINCARIOL        (Photo credit should read Miguel Schincariol/AFP via Getty Images)
