The State Commission of Truth of São Paulo have published a book called Bagulhão: A Voz dos Presos Políticos contra os Torturadores (“Bagulhão – The Voice of Political Prisoners against Torturers”), a valuable insight into the military dictatorship in Brazil. The book, which was released on Monday (June 16), is based on a letter written by political prisoners at the Romão Gomes penitentiary in São Paulo in 1975, which mentioned the names and aliases of 233 torturers acting under the military rule in the country.
