One thing I find interesting about that sequence is Grace Hamilton's comment upon seeing the Ant: "What is a guy like that doing at Michael Corleone’s house?"
That a reporter would show surprise at a "spooky looking guy" being at Michael's house indicates how successful Michael was at projecting a veneer of legitimacy and insulating himself from the street-level Mafia.
"A man in my position cannot afford to be made to look ridiculous!"
