"Riina, like Badalamenti and Provenzano, was a central figure not only in the mafia affairs dealt with in the trials, but also in what Giovanni Falcone called "the Big Game". That is, that part of the history of power which was played out behind the scenes, through violent acts such as massacres and murders carried out by Mafia members, but not solely in the Mafia’s interest: such as the murder of Carlo Alberto Dalla Chiesa."
