Nobody called Bill Cutolo 'Billy Fingers' in real life, despite the papers using it sometimes.
And speaking of that crew, no one calls Dom Dionisio 'Black Dom', he was always called 'N-word Dom', or just 'Big Dom'. I'm guessing that ended up sanitized for public consumption by wtiters along the way. Back in grade school days where he got the name nobody gave a shit about being PC.
Except his wife.
If you catch my drift.
