America's founding fathers had seen those issues.
That is why they had wrote the Constitution as what we have now.
They want people have freedom in multiple aspects:
Financial freedom that government can not steal people's wealth through inflation, that is why they wrote money shall be gold and silver in constitution.
They want people to stands for they basic rights against tyrany of government so they put freedom to carry weapons in the Constitution.
They want people to have freedom of speach and freedom of religion so they put it in first amendmend.
The following quotes by the authors of the Second Amendment, their contemporaries, various state and federal courts, and others should be useful in the debate over whether that amendment protects a right of individuals or only the military.
--------------------------------------------------------------------------------
The Second Amendment states: "A well regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms shall not be infringed."
--------------------------------------------------------------------------------
"On every question of construction (of the Constitution) let us carry ourselves back to the time when the Constitution was adopted, recollect the spirit manifested in the debates, and instead of trying what meaning may be squeezed out of the text, or invented against it, conform to the probable one in which it was passed." (Thomas Jefferson, letter to William Johnson, June 12, 1823, The Complete Jefferson, p. 322)
"The whole of the Bill (of Rights) is a declaration of the right of the people at large or considered as individuals.... It establishes some rights of the individual as unalienable and which consequently, no majority has a right to deprive them of." (Albert Gallatin of the New York Historical Society, October 7, 1789)
"The right of the people to keep and bear arms has been recognized by the General Government; but the best security of that right after all is, the military spirit, that taste for martial exercises, which has always distinguished the free citizens of these States....Such men form the best barrier to the liberties of America" - (Gazette of the United States, October 14, 1789.)
"No Free man shall ever be debarred the use of arms." (Thomas Jefferson, Proposal Virginia Constitution, 1 T. Jefferson Papers, 334,[C.J.Boyd, Ed., 1950])
"The right of the people to keep and bear...arms shall not be infringed. A well regulated militia, composed of the body 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])
"A militia, when properly formed, are in fact the people themselves...and include all men capable of bearing arms." (Richard Henry Lee, Additional Letters from the Federal Farmer (1788) at 169)
"What, Sir, is the use of a militia? It is to prevent the establishment of a standing army, the bane of liberty.... Whenever Governments mean to invade the rights and liberties of the people, they always attempt to destroy the militia, in order to raise an army upon their ruins." (Rep. Elbridge Gerry of Massachusetts, spoken during floor debate over the Second Amendment [ I Annals of Congress at 750 {August 17, 1789}])
"...to disarm the people - that was the best and most effectual way to enslave them." (George Mason, 3 Elliot, Debates at 380)
"Americans have the right and advantage of being armed - unlike the citizens of other countries whose governments are afraid to trust the people with arms." (James Madison, The Federalist Papers #46 at 243-244)
