In AZ if you get out of your car to confront someone, you are automatically, legally on the wrong side of whatever happens next. What you did is called "defensive display" here and is totally legal. It is best that you call the cops before the other guy does, as they tend to see the victim as the first person who calls them. You don't want to be the second guy who calls them with a first guy who can describe your gun to them.
