Much of what you need to know about this "well written article" can be summed up with these 2 paragraphs.
"Hold that thought, because when the text is considered to be not as clear as it needs to be, the textualist then is able to hunt for more information — in history, traditions and, if things are still murky, in more esoteric areas, say, sea shanties. (Okay, likely not sea shanties, unless the statute has to do with, say, whaling or piracy. Then maybe so.)
Speaking of militias, the Militia Act of 1903, also known (somewhat hilariously) as the Dick Act, for Ohio congressman Charles Dick, was passed after militia groups sent by states proved untrained and disorderly and generally lacking standards (e.g., different uniforms) during the Spanish-American War. Unfortunately, the act mentioned the creation of both an "organized" and an "unorganized" militia, and thereby confused the issue. "
It sure convinced me.............. of nothing.
