"The Mafia today is more of a federation and less of an authoritarian state," according to anti-Mafia prosecutor Antonio Ingroia of the Direzione distrettuale antimafia (DDA) of Palermo, referring to the previous period of authoritarian rule under Salvatore Riina. Provenzano "established a kind of directorate of about four to seven men who met very infrequently, only when necessary, when there were strategic decisions to make."
