The D'Amico's are a far cry from the Rizzutos or New York and Toronto clans. Which is why this whole beef started in the first place. The Rizzutos didn't care to pay up and knew there would be no real reprecussions if they didn't pay them but what they soon found out is the D'Amico clan had guys with big nuts and very big nuts. So either you settle or go to war with a bunch of guys that have nothing to lose. The Rizzutos would have never lost the war but it wasn't worth possibly losing some key guys. The AK from the helicopter was purley to demonstrate how above the Rizzutos were in comparison to the D'Amicos.

Granby is a hick french town. They are close to the border and can smuggle very easily which is how they got in to business in teh first place but this also gives them access to cash and guns but the D'Amicos are losers in the Underworld.
