None of Capone's biographers says he was a made man, nor do they associate the Outfit under Torrio and Capone with the Mafia. And with good reason: neither was Sicilian at a time when Mafia meant Sicilian. There was a Mafia of sorts in Chicago at the time--the Unione Siciiliana, a kind of civic association with muscle. Capone treated them with respect, and constantly tried to get his own Sicilian guys to head the Unione.
You shouldn't so easily dismiss what HairyKnuckles pointed out. There's a lot of misinformation about Capone and the Unione Siciliana. I dealt with some of this in an article I wrote called "The Dreaded D'Andrea" in Informer journal. And just because previous biographers have neglected Capone's connection to Masseria doesn't mean that future ones won't. I can guarantee that.
