I agree with Turnbull, Cicci's testimony doesn't really hurt Michael as much as Pentangelli's had the potential to. At least what we heard in the movie. Hopefully, Michael gave him a pass. Granted, that is a somewhat fanciful thought given that Michael had turned into someone who sought venegance on everyone who remotely crossed him, even some who didn't. I choose to think that Cicci was smart and vanished somewhere into the wilderness of America and opened a nice Italian restaurant somewhere like Greenville, Mississippi. Cicci was cool, if a killer and a thug can be termed as such.
