2nd Amendment Saturday

Thanks to David and his inspiring blog, the War on Guns, I have decided to post something in relation to one of our enumerated rights, the 2nd Amendment, every Saturday.

A well regulated militia being necessary to the security of a free State, the right of the People to keep and bear arms shall not be infringed.

"The Constitution preserves "the advantage of being armed which Americans possess over the people of almost every other nation. . . (where) the governments are afraid to trust the people with arms." --James Madison, The Federalist, No. 46

"When the resolution of enslaving America was formed in Great Britain, the British Parliament was advised by an artful man, who was governor of Pennsylvania, to disarm the people; that it was the best and most effectual way to enslave them; but that they should not do it openly, but weaken them, and let them sink gradually.". . . I ask, who are the militia? They consist now of the whole people, except a few public officers." --George Mason, Virginia's U.S. Constitution ratification convention, 1788

"No freeman shall ever be debarred the use of arms." --Thomas Jefferson, Proposed Virginia Constitution, June, 1776

"The said Constitution shall be never construed to authorize Congress to infringe the just liberty of the press, or the rights of conscience; or to prevent the people of the United States, who are peaceable citizens, from keeping their own arms." --Samuel Adams, Massachusetts' U.S. Constitution ratification convention, 1788

I don't know where in the Constitution the government is allowed to extensively limit, and further define an enumerated right is.
