(1) Note: The militia referred to is every able bodied male age 17 to 45 under federal law (10 U.S.C. 311). It is not the National Guard which didn't even exist until 116 years after the Second Amendment was adopted.
You will note from the foregoing that the powers of the Congress, Senate and President are very limited. We the People have the right to determine the direction the country shall take.
It is your duty as a Citizen of the United States to take an active part in the governance of this country. It behooves you to obtain a copy of the Constitution and Bill of Rights to learn your rights and duties because We the People should control the destiny of the only government in the history of mankind that provides its citizens the extent of freedom that our Constitution and Bill of Rights provides.
