most clear and undeniable

For those of you interested in the legal argument, the right to bear arms is recognized in the Constitution, not created by the Constitution. The right is thought of in legal philosophy, as pre-existent and natural. From the court opinion at

England’s Bill of Rights of 1689 guaranteed “[t]hat the Subjects, which are Protestants, may have Arms for their Defence, suitable to their conditions, as allowed by law.” 1 W. & M., Sess. 2, c. 2. Here too, however, the right was not newly created, but rather recognized as part of the common law tradition. The ancient origin of the right in England was affirmed almost a century later, in the aftermath of the anti-Catholic Gordon riots of 1780, when the Recorder of London, who was the foremost legal advisor to the city as well as the chief judge of the Old Bailey, gave the following opinion on the legality of private organizations armed for defense against  rioters:

The right of His majesty’s Protestant subjects, to have arms for their own defence, and to use them for lawful purposes, is most clear and undeniable. It seems, indeed, to be considered, by the ancient laws of the Kingdom, not only as a right, but as a duty; for all the subjects of the realm, who are able to bear arms, are bound to be ready, at all times, to assist the sheriff, and other civil magistrates, in the execution of the laws and the preservation of the public peace. And that right which every Protestant most unquestionably possesses, individually, may, and in many cases must, be exercised collectively, is likewise a point which I conceive to be most clearly established by the authority of judicial decisions and ancient acts of parliament, as well as by reason and common sense.
