"The right of the people to keep and bear ... arms shall not be infringed. A well regulated militia, composed of the body of the people, trained to arms, is the best and most natural defense of a free country
..." -- James Madison, I Annals of Congress 434, June 8, 1789
"The militia is the natural defense of a free country against sudden foreign invasions, domestic insurrections, and domestic usurpation of power by rulers. The right of the citizens to keep and bear arms has justly been considered, as the palladium of the liberties of the republic
; since it offers a strong moral check against the usurpation and arbitrary power of rulers
; and will generally ... enable the people to resist and triumph over them."
-- Joseph Story, Supreme Court Justice, Commentaries on the Constitution of the United States, p. 3:746-7, 1833
