May 23 marks the 21st anniversary of the murder of the anti-Mafia Judge Giovanni Falcone, his wife Francesca Morvillo and their three bodyguards, blown up by 500 kilos of dynamite on the highway between the airport at Puna Raisi and the city of Palermo. Most of those considered responsible are in prison. But what is believed to lie behind his murder, and that months later of his fellow magistrate Paolo Borsellino, is still being analyzed by Palermo magistrates investigating allegations that an illegal secret pact had been forged between the government and the Mafia. In the words of Palermo's chief prosecutor, Roberto Scarpinato, "We must take cognizance that the Mafia evil is not outside of us, but also among us."
