<p>The SCOTUS has already ruled that A2 articulates a preexisting personal right.</p>
<p>In Miller [FindLaw</a> for Legal Professionals - Case Law, Federal and State Resources, Forms, and Code](<a href=“http://caselaw.lp.findlaw.com/scripts/getcase.pl?navby=case&court=us&vol=307&invol=174]FindLaw”>http://caselaw.lp.findlaw.com/scripts/getcase.pl?navby=case&court=us&vol=307&invol=174) we find that the SCOTUS said:</p>
<p> The Constitution as originally adopted granted to the Congress power- ‘To provide for calling forth the Militia to execute the Laws of the Union, suppress Insurrections and repel Invasions; To provide for organizing, arming, and disciplining, the Militia, and for governing such Part of them as may be employed in the Service of the United States, reserving to the States respectively, the Appointment of the Officers, and the Authority of training the Militia according to the discipline prescribed by Congress.’ U.S.C.A.Const. art. 1, 8. With obvious purpose to assure the continuation and render possible the effectiveness of such forces the declaration and guarantee of the Second Amendment were made. It must be interpreted and applied with that end in view.</p>
<p>The Militia which the States were expected to maintain and train is set in contrast with Troops which they [307 U.S. 174, 179] were forbidden to keep without the consent of Congress. The sentiment of the time strongly disfavored standing armies; the common view was that adequate defense of country and laws could be secured through the Militia- civilians primarily, soldiers on occasion.</p>
<p>The signification attributed to the term Militia appears from the debates in the Convention, the history and legislation of Colonies and States, and the writings of approved commentators. These show plainly enough that the Militia comprised all males physically capable of acting in concert for the common defense. ‘A body of citizens enrolled for military discipline.’ And further, that ordinarily when called for service these men were expected to appear bearing arms supplied by themselves and of the kind in common use at the time.</p>
<p>Blackstone’s Commentaries, Vol. 2, Ch. 13, p. 409 points out ‘that king Alfred first settled a national militia in this kingdom’ and traces the subsequent development and use of such forces.</p>
<p>Adam Smith’s Wealth of Nations, Book V. Ch. 1, contains an extended account of the Militia. It is there said: ‘Men of republican principles have been jealous of a standing army as dangerous to liberty.’ ‘In a militia, the character of the labourer, artificer, or tradesman, predominates over that of the soldier: in a standing army, that of the soldier predominates over every other character; and in this distinction seems to consist the essential difference between those two different species of military force.’ </p>
<p>Here we find in Miller who is the Militia, what the Militia is supposed to do and where arms for the Militia originate. We also note that Miller plainly states that the arms are to be that in common use at that time.</p>
<p>It would be very reasonable to assume that periodic training would be required for everyone owning firearms. Personally, I don’t find that a bad idea.</p>
