Crosses are seen in front of the School of Law of the University of Sao Paulo (USP) in homage to the inmates dead at the Carandiru Penitentiary massacre in Sao Paulo, Brazil on April 8, 2013. Twenty-six military police officers were to go on trial here Monday for the alleged execution-style killing of inmates during Brazil's deadliest prison uprising, which claimed the lives of 111 prisoners.
