It’d be open season on mexicans found in the desert with no daily limit or bag limit.
As another poster said, “it’d be an act of war”.
My thoughts exactly. We live in southern AZ, not far from the border. We already attempt to stop and hold for border patrol pick-up any illegals crossing the ranch. It usually takes the bp about an hour to get to our semi-remote location. And we do indeed not leave the house without being armed, usually with pistol and rifle (or 12 gauge) both.
You would have a lot of backup from the rest of us Arizonans too.
