"The right of self-defense is the first law of nature; in most governments it has been the study of rulers to confine this right within the narrowest possible limits. ... and [when] the right of the people to keep and bear arms is, under any color or pretext whatsoever, prohibited, liberty, if not already annihilated, is on the brink of destruction." - St. George Tucker
