The medical and public health scholarship on firearms reads differently from criminological scholarship on such. The high school shootings that incited recent gun paranoia occurred five years after the conviction-free Brady bill passed. When guns were readily available even to teens in the 1960s, there were no high school shootings. Constitutional law scholars, who have found everything from abortions to prohibitions on nativity scenes in the U.S. constitution, become strict constructionists when it comes to the Second Amendment and interpret it as giving the right to carry muskets if and when tyranny arises. The Second Amendment has a rich history in the English Bill of Rights of 1689 which reflected the scholarly writings of that era on arms as a root source of power.
Tyranny occurs because the citizenry are unarmed.
Jefferson wrote of the personal and societal virtue of a gun as a constant companion. Defending the home front by asking a thief to stay in abeyance as one calls in committee security is nonsense. Further, the amendment is grouped with the three which deal with individual freedoms, not societal rights. Everyone who is able may have a gun. A collective right theory is strained beyond reason, but court cases to date evidence a liberal judiciary dismissive of the jurisprudential history and context of this amendment despite their ability to read birth control rights into the Fourth Amendment.
