Actually the article is very inaccurate and full of assumptions. It also has the "incorrect" version of the second Amendment, the one that has the magically appearing third comma. In the article it quotes
The Second Amendment reads: "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."
There is no comma between arms and shall. The correct version can be determined by looking here. It is the original final text version that was used to determine which of the articles would be included in the bill. It has all twelve Articles, of which two were omitted.
Yeah, that comma keeps on coming back, no matter how many times we try to banish it. It was in the graphic last night on the Newshour on government TV. I think they made up a graphic of the 2A JUST to put that comma on the screen, since it really served no other purpose in the story.
It does not say the right of the people who are in the militia to keep and bear arms.
