Henderson's second insight was that despite the right belonging to "the people" in the amendment, it actually belonged only to the militia as an organized military force. To believe this, you have to believe that the United States is the only nation on Earth that felt a need to guarantee its government, in writing, the right to have an army -- which is possible, I suppose, if Jefferson foresaw the attitude of the modern Democrat party towards the military.
The Second Amendment is an individual right. Just like the 1st, 3rd, 4th, etc. The founding fathers didn't like the idea of a standing army, why would they think they'd need to put provisions for one in a document pertaining to individual rights?
"The constitutions of most of our States assert that all power is inherent in the people; that... it is their right and duty to be at all times armed;..." Thomas Jefferson letter to Justice John Cartwright, June 5, 1824. 1824. ME 16:45.
"As civil rulers, not having their duty to the people duly before them, may attempt to tyrannize, and as the military forces which must be occasionally raised to defend our country, might pervert their power to the injury of their fellow citizens, the people are confirmed by the article in their right to keep and bear their private arms."
