where are yo getting 'and'?which version?
As passed by the Congress and preserved in the National Archives:
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, then-Secretary of 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.
It's kind of funny, if you read all the proposed wording, it becomes clear the word militia meant military, and not everyone being armed.
"A well regulated militia, composed of the body of the people, being the best security of a free state, the right of the people to keep and bear arms shall not be infringed; but no one religiously scrupulous of bearing arms shall be compelled to render military service in person."
