>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.
Well regulated means well armed. Militia means citizen army, and the people means the people.
It is hard to come to a different understanding of the amendment without redefining these terms.
My understanding is that those favoring a living constitution focus on the purpose or why of the amendment was there, and and that a citizen militia is not longer necessary.
