I am as baffled by the killing of the gunmen as anyone.
BTW, plawrence: I believe that Neri pushed past Rocco in the family hierarchy. I didn't suggest that Rocco was jealous. I did mention another poster's comment that he (the poster) had seen an earlier script treatment in which Rocco volunteered for the one-way mission at the end out of guilt because he was involved in the Tahoe attack.
