Count to ten.
Find it HERE and by all means search inside.
As for meaning what it says .. well here is one example and a further explanation.
I picked this at random, BTW. It could be any of the 1st 10, that annoying Bill of Rights thing that right wing nut Jefferson insisted on to Madison from France.
What did Jefferson think this meant?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.
In a nation governed by the people themselves, the possession of arms to defend their nation against usurpers within and without was deemed absolutely necessary. This right is protected by the 2nd Amendment to the Constitution. A gun was an everyday implement in early American society, and Jefferson recommended its use. "A strong body makes the mind strong. As to the species of exercises, I advise the gun. While this gives moderate exercise to the body, it gives boldness, enterprise and independence to the mind. Games played with the ball, and others of that nature, are too violent for the body and stamp no character on the mind. Let your gun, therefore, be the constant companion of your walks." --Thomas Jefferson to Peter Carr, 1785. ME 5:85, Papers 8:407
"The constitutions of most of our States assert that all power is inherent in the people; that... it is their right and duty to be at all times armed." --Thomas Jefferson to John Cartwright, 1824. ME 16:45
"One loves to possess arms, though they hope never to have occasion for them." --Thomas Jefferson to George Washington, 1796. ME 9:341
Now, I would think that this is clear enough for us here 230+ years in the future to INTERPRET rather unambiguously, unless we wish to simply say that we can, by popular fiat of the day, interpret all words in the Constitution in any way facile at any given moment for any given purpose we can use words and rationalizing to justify.
As Mr. Sunstein clearly feels he can tortuously guide us and transform us to think.
As for me, I'll take the old white guy from Virginia who took a chance on being hung to have his say.
