To further the sloppiness of this Vincent makes it clear at the meeting in Sicily that the Corleones have to get back into NY or else the Colombians will move in. I don't think he was worried about the Colombians taking over the numbers rackets or the unions.
"Io sono stanco, sono imbigliato, and I wan't everyone here to know, there ain't gonna be no trouble from me..Don Corleone..Cicc' a port!"
"I stood in the courtroom like a fool."
"I am Constanza: Lord of the idiots."
