I don;t see how history can discover the reasoning/interpretation/intent every single citizen of the 11 states that ratified the Bill of Rights.
Its the history of those people and putting our best guess as to how they understood the power of government and the people that should control. While the intent of the so-called "founding fathers" might be helpful, they are far from the source of power and therefore their intent is no more important than that Joe Blow from Newark.
