Turnball, et al:

I actually respectfully disagree with the premise that (in this scenario) Michael displayed "Sicilian cunning". To a previous poster's point: If Michael had not ducked he would have been killed and all that cunning (which did not previously tell him Roth was after him) would have been spilled over the bed and floor.

Michael did however (IMHO) display "Sicilian cunning" (as did his father) when he authored the murder plan for Sollozo (his father: Fanucci).

In Michael's response to the Tahoe hit - it is much of "these Italians can smell this a mile away" as Al Pacino reported in "Carlito's Way" after the lawyer killed a mob boss. It is the putting the pieces of the puzzle together quickly and correctly and responding accordingly that Michael displayed, i.e., "these Italians can smell this a mile away".

Just my opinion.
