Thomas Jefferson asserted that "the strongest reason for the people to retain the right to keep and bear arms is, as a last resort, to protect themselves against tyranny in government" (Thomas Jefferson Papers,p. 334, 1950). According to Alexander Hamilton, "f the representatives of the people betray their constituents, there is then no recourse left but in the exertion of that original right of self-defense which is paramount to all positive forms of government."
Several Founders wrote of the importance of maintaining an armed citizenry. Thomas Jefferson felt strongly that "[n]o free man shall ever be debarred the use of arms.” (Thomas Jefferson Papers, 334) Zacharia Johnson, delegate to Virginia Ratifying Convention, agreed that "the people are not to be disarmed of their weapons." Samuel Adams even pushed for an amendment stating that the "Constitution shall never be construed... to prevent the people of the United States who are peaceable citizens from keeping their own arms" (Phila. Independent Gazetteer, August 20, 1789).
James Monroe was assured that, if the right to keep and bear arms was “well defined, and secured against encroachment, it [would be] impossible that government should ever degenerate into tyranny." James Madison felt confident that "Americans need never fear their government because of the advantage of being armed."
