Aristotle wrote in Politics that oligarchs and tyrants “mistrust the people, and therefore deprive them of arms.” Rulers will, according to Tucker, try to confine the “right of self-defense within the narrowest limits possible. Wherever standing armies are kept up, 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" (Henry St. George Tucker, Blackstone's 1768 Commentaries on the Laws of England).
