the Second Amendment refers to "the right of the people to keep and bear arms," and every other part of the Bill of Rights that uses that phrase has, since time immemorial, been interpreted as referring to an individual right held by all citizens, as opposed to some sort of state power or "right" held by the state and its institutions (e.g. its militia). It would require major verbal gymnastics to interpret a "right of the people" as anything other than an individual right vested in every member of "the people."
the amendment's backers may well have believed that the effectiveness of the militia was best served by individual gun ownership.
I think this is correct (both of you). The eighteenth-century militias were not standing armies, but ad hoc fighting forces made up of farmers and others who had weapons and were willing to fight. Thus, to have a viable militia, it was necessary for individuals to own weapons.
3. in order to answer that question, there need to be certain criteria for distinguishing between weapons that are constitutionally protected, and those that are not.
4. in defining those criteria, it would seem logical to refer to the "prefatory clause" that specifies the purpose for which the right is protected.
And as I said above, the fact that the right has this particular purpose does not necessarily make that its only purpose. But for determining whether ownership of a particular kind of weapon is protected by the amendment, shouldn't an explicitly stated purpose carry at least as much weight as an implicit one?
I think you're hoisted by your own petard, here. When he was in the military, my husband was issued a handgun, a .45.
the Supreme Court has made further argument pointless
No more so than argument over the existence of a right to privacy.
Exactly. Many people argue that the Supreme Court created a right to privacy out of whole cloth (they do not accept the "penumbra" analysis). We can argue all we want, but the right currently exists and will continue to do so until the Supreme Court says it doesn't. (In the meantime, its scope may shrink and expand with each new decision.)
At the same time, such argument is important, which is why we have a First Amendment. Our job, as citizens, is to each try to make the best argument we can for our views, in hopes that the most sound arguments will eventually prevail. The Supreme Court, while often hard of hearing, is not entirely deaf to the sensibilities of the public.
As I have repeated countless times now, even if we accept the premise that the right is an individual one, it is far from clear why that right should extend to handguns, except for the fact that today, five justices happen to think that it should. That's hardly a solid constitutional argument: if in ten years five justices disagree, they will have little difficulty explaining why they reverse Scalia's ruling.
Yes, that possibility is integral to the notion of the Constitution as a living document that reflects the needs of the times. The Court has the power to say it was mistaken. That's how
Plessy v. Ferguson (the "separate but equal" ruling upholding segregation) was overturned by
Brown v. Board of Education, and
Bowers v. Hardwick was overturned 17 years later by
Lawrence v. Texas (which ruled that sodomy laws were unconstitutional).
P.S. I can't help it; I'm an academic married to a lawyer (double whammy) and thus feel compelled to provide citations:
