"In sum, the historical record from the relevant period shows that our Nation did not regard concealed carry and open carry as interchangeable. The right to keep and bear arms did not extend to the carrying of weapons in secret, which was regarded as the practice of the cowardly and the disreputable and as incompatible with the legitimate exercise of the right of self-defense. Open carry, by contrast, was understood to be the manner of bearing arms that gave full effect to the rights secured by the Second Amendment." View quoted note →
