Biden Is Cracking Down On Guns Again With AR-15 Pistol Ban, And He’s Using Heller To Do It
However, as explained here, Heller erred in at least two respects. First, it misinterpreted the Supreme Court’s decision in U.S. v. Miller (1939). Miller indicated that the right to keep and bear arms includes all arms that “have some reasonable relationship to the preservation or efficiency of a well-regulated militia,” such as those that are “part of the ordinary military equipment” and any others the use of which “could contribute to the common defense.”
Miller also noted that militiamen were historically “expected to appear bearing arms supplied by themselves and of the kind in common use at the time,” so Heller ignored the discussion of military and militia arms and instead concluded that Miller limited the right to arms to those “in common use.”
Also, Heller flat-out lied about so-called “dangerous and unusual weapons” laws, referred to by the DOJ. By way of background, the English Statute of Northampton (1328) prohibited people from carrying arms in affray of the peace, and in 1696 an English court interpreted that law to prohibit being armed, not in general, but for the purpose of terrorizing people. William Blackstone, in his famous 1769 Commentaries on the Laws of England, was first to use the phraseology “dangerous and unusual weapons” in this context, writing that the “[t]he offence of riding or going armed, with dangerous or unusual weapons, is a crime against the peace, by terrifying the good people of the land.”
