Aguila, the case was In Re Brickey, 8 Idaho 597 (1902).
Here, the Idaho Supreme Court interpreted our own RKBA and the 2A as an individual right to carry for defense of self, family and property. The Court went on to say that the State could regulate (to death) the practice of concealed carry but could not forbid the open carrying of lawful arms.
This case has been mentioned in passing by Gura in many of his briefs, but he has never gone into detail. Perhaps at some point, he will. I say this, because it stands as good law in the fight for carry in some form, openly or concealed.
