The 2cnd Amdt to the USC,
As passed by the Congress:
"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."
As ratified by the States and authenticated by Thomas Jefferson, Sec-State:
"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."
Notice the missing commas, some say that the British changed the document during the War of 1812,
When-while they had control of the White House and all of the important founding documents that were kept there.
The 2cnd-Amdt is the only amdt to the USC which states a purpose !
