The Right To Bear Arms

 Back when the Bill of Rights was written, the flint-lock muzzle-loaded musket was the deadliest weapon, after the cannon, around.  If Congress was willing to allow Americans to own and use the deadliest weapons of their age, then, from an originalist perspective, 21st Century Americans should be allowed to own nuclear weapons, F-22 fighter jets, Abrams tanks, nuclear submarines, ICBMs, cruise missiles, etc., as well as sawed-off shotguns, unmodified or modified AR-15s and Glock 19s.  All dangerous weapons, yes, but if we follow the Founders' original intent, the ownership or possession of these weapons should not be restricted; just as the ownership or possession of flint-locks and cannon was not restricted according to the Second Amendment.

But the Second Amendment has a clause which is preeminent to the "right to bear arms" clause, and that begins, "A well regulated Militia, being necessary to the security of a free State....".

Article II, Section 2.  "To raise and support Armies, but no Appropriation of Money to that Use shall be for a longer Term than two Years;

To provide and maintain a Navy;"

 A land army had to be reauthorized every two years, but a standing navy was desired.

The only way to stop a bad man with a gun is to take away his gun.

Since all men a sinful, and therefore bad, all men should be disarmed.
