Justice Joseph Story, in his 1833 “Commentaries on the Constitution:”
The right of the citizens to keep and bear arms has justly been considered as the palladium of the liberties of a republic; since it offers a strong moral check against the usurpation and arbitrary power of rulers; and will generally, even if these are successful in the first instance, enable the people to resist and triumph over them.
Thanks, another good one to save to my Second Amendment “Quotes” file!
