Excuse me, but what is the US Constitution's Second Amendment for, exactly?
"No free man shall ever be de-barred the use of arms. The strongest reason for the people to retain their right to keep and bear arms is as a last resort to protect themselves against tyranny in government." --Thomas Jefferson
"That the people have a right to keep and bear arms; that a well regulated militia composed of the body of the people trained to arms, is the proper. natural and safe defense of a free State. That standing armies in time of peace are dangerous to liberty, and therefore ought to be avoided, as far as the circumstances and protection of the community will admit; and that. in all cases, the military should be under strict subordination to and governed by the civil power." --George Mason
"The said constitution shall never be construed to authorize Congress to prevent the people of the United States who are peaceable citizens from keeping their own arms." --Samuel Adams
"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
"Are we at last brought to such a humiliating and debasing degradation that we cannot be trusted with arms for our own defense? Where is the difference between having our arms under our own possession and under our own direction, and having them under the management of Congress? If our defense be the real object of having those arms, in whose hands can they be trusted with more propriety, or equal safety to us, as in our own hands?" --Patrick Henry
"[A]rms like laws discourage and keep the invader and the plunderer in awe, and preserve order in the world as well as property. The balance of power is the scale of peace. The same balance would be preserved were all the world destitute of arms, for all would be alike; but, since some will not, others dare not lay them aside. And while a single nation refuses to lay them down, it is proper that all should keep them up." --Thomas Paine
