In Andrew DiDonato’s book ‘surviving the mob’ it mentions that Nicky Corozzo wanted to kill him.

“Nicky turned to me and made the sign of a gun with his thumb and finger. He said if he did get arrested, there’d be a lot of work [killing] to do. Then he looked around at everybody and he said, ‘Do you hear me? I said if I get arrested, there’s gonna be a lot of fuckin’ work to do.’ “Nicky grabbed my hand and said, ‘And we’re gonna start with that fuckin’ Baby Huey in Queens.’ Baby Huey was what we called Junior Gotti. Nicky looked at me and Mike Yannotti. He said, ‘Okay. Start gettin’ familiar with this guy.’ Mike nodded. I said sure, whatever had to be done would be done.

I don’t think that book mentions anything other than that so in this instance I don’t think it was anything other than talk.
