I don't think so. The difference between Gianna and Santino is that Santino was in the Continental, while Gianna was not. Even if they frowned upon Gianna's death, the High Table had no standing to go after John until he killed Santino. Even they have to follow the rules.
I live in Chicago everyone has a gun....lived in Iowa when I was in my 20s. I remember going over to my friend's house to help his dad cut down a tree to use as backstop for the firing range he was building on their farm.
