"I have focused my recollections on Schifani and spoke to the magistrates about him because even before the attack at the Olimpico I knew there were State-Mafia negotiations. When I saw Schifani on television and in political office, it occurred to me that he often frequented the warehouse in Brancaccio, Palermo, where Filippo Graviano used to stop for meetings. And I surmised that Schifani might have been the link in the negotiations."
