By 1972 , Gianfranco Sanguinetti and Guy Debord were the only two remaining members of Situationist International . Working with Debord , in August 1975 , Sanguinetti wrote a pamphlet titled '' Rapporto veridico sulle ultime opportunità di salvare il capitalismo in Italia '' ( Eng : '' Veritable Report on the Last Chances to Save Capitalism in Italy '' ) , which ( inspired by Bruno Bauer ) purported to be the cynical writing of " Censor " , a powerful industrialist . The pamphlet argues that the ruling class of Italy supported the Piazza Fontana bombing and other mass slaughter , for the higher goal of defending the capitalist status quo from communist claims . The pamphlet was mailed to 520 of Italy 's most powerful individuals . It was received as genuine , and powerful politicians , industrialists and journalists praised its contents and guessed the identity of its high-profile author . After reprinting the tract into a small book , Sanguinetti revealed himself to be the true author . Under pressure from Italian authorities , Sanguinetti left Italy in February 1976 , and was denied re-entry to France , from which he had previously been deported in 1971
