abc123, The Government had nothing to do with Nicoletti being killed. They didn't care about Nicoletti at all.

Auippa/ Cerone killed Giancana in 1975. They couldn't kill Nicoletti right away. Everyone was on guard. Besides, in 1975, they may not have decided for sure if they were going to kill Nicoletti.

Sometimes, people change their attitude or loyalty for different reasons. Dominic Blasi, Turk Torello, Joey Lombardo all had a different way of looking at it in 1975, compared to 1963.

Also, it was a little bit a time to test him and see his reaction and hear what he had to say about it from other men.

They then decided Nicoletti had to go. You really can't understand the street dynamics that went on during this time, unless you were there and know the people involved. You'll never understand all the dynamics reading it in a book. Anyway, that's the reason he was killed in 1977 and not 1975.
