After just liberating themselves from what was viewed a tyrannical strong centrally powered government...here comes Maddison and co proposing a centralized government to men of individual states where they governed. It was a hard sell....and probably a hard swallow. Lets remember, the Red coats in England were not comprised of malitia, or national guard units from individual states. Englands soldiers were directly formed and in the employ of the King and the Central Government. It seems logical then that the States, their officials and their residents were aprehensive on the notion of centralized government as it seems logical that the selling point for Madison and Co was to say...you get to keep and form your own well organised, regulated malitia made of your people to protect your self and your state from the central government we are proposing. Further, the central government can not infringe on that right. There is no evidence or reason for Maddison or the States to even talk about Joe Smith owning fire arms to protect himself from Bob Jones. That problem of Joe shooting Bob did not exist, and to suggest that the second amendment addresses Joe and Bob protecting themselves from each other as individuals just does not make any sense. It seems More plausible that it was the Central government saying to the people of each State, you have a right to protect yourself from the central government by forming your own well regulated (Well practiced and prepared) Malitia, and nothing about Joe or Bob owning guns.
