Around 5000 members ,as i said already , in Italy you are guilty until proven otherwise , a lot of people arrested in this big busts,later they set them free. Also this is all easily replaceable street people,people who are brains behind mafia,never gets arrested, i do agree that Sicilian Mafia is much weaker than it was in 1980-2000,but they will never see that power again,that time is over.
