Yes. That's him.
Remember when DeNiro was saying he knows guys that pay him nothing?
Someone ...... "the Greek"
And ...... someone at something street..
Were they predecessor to black hand?
lol
Your asking the correct person
It's actually Genco, Vito's friend (later his consigliere), who says that Fanucci is Black Hand
It's debateable whether Fanucci was actually "Black Hand"
- As you mentioned Vito says "Joe the Greek on Tessimo Avenue, Frank Pennitanlo, and Tachinko Schrabo. They don't pay Fanucci."
-Fanucci never has bodyguards, and is attacked by street punks
-When Vito tries to negotiate, Fanucci says something along the lines of : "If you refuse, the police will come and you'll be arrested"
-He accepts Vito lesser amount of money
- There are no reprisals to his assassination
None of the above would have occurred if Fanucci was Black Hand
So I believe Fanucci is just the neighborhood bully and has no real connection to the Black Hand/La Cosa Nostra/Mafia.
