"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."
