You sure are funny. Here is the 4th Amendment:
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
And here, for the record, is "Article the fourth" of the original Bill of Rights, two of which were apparently not ratified:
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.
We call it Amendment II now, since it was the second one in this list which was ratified.
However, here is what you cited to me way back in your post #51:
Article IV : Section 2. The Citizens of each State shall be entitled to all Privileges and Immunities of Citizens in the several States
As you can see, this is neither "the Fourth Amendment" nor is it "Article the fourth" of the Bill of Rights (the Second Amendment).
It is the opening of Article IV, Section 2 of the Constitution. Just like you correctly said in your post #51.
Get it?
Ah no. Sorry but you are wrong.
That's why they're called amendments; look the word up, it means an addition to... something.
It does not become an entity on its own, a separate item in itself, it just makes the original longer or bigger.
That the first 10 amendments are referred to as the "Bill of Rights", is a semantic convenience to identify them as the first ten, adopted at the same time as the main body of the Constitution when it was officially adopted (but not yet ratified).
