The right of the people to keep and bear... arms shall not be infringed. A well regulated militia, composed of the people, trained to arms, is the best and most natural defense of a free country... - James Madison, I Annals of Congress 434, June 8, 1789.
Oh, had our second amendment only been phrased as this!
The composition of the militia is defined in the US Code. E It is composed of the Organized militia and the unorganized militia. The unorganized militia being the point of interest because it is legally defined as all abled bodied males between 17 and under 45 years of age. Many liberal groups try to argue that the 2nd amendment is a collective right. If it is then at the very least the following people are allowed to have guns.
U.S. Code : Title 10 : Section 311
