Let’s say that a future government has decided to incarcerate wrong thinking people into “reeducation camps,” to try to get people thinking right, and to quietly “take care” of all those who can’t be rehabilitated. Free speech is suppressed, the media made an arm of the state, and the government refuses to stand for free and fair elections. In that situation, most people would recognize the government has forfeited any claim to legitimacy. We fought a World War, and a risky, expensive, and protracted cold war against such governments. Most people, I would wager, would agree such a government ought to be resisted, and violently if necessary. But I have to question how some view the form that would take on.
Do folks really believe that if the proverbial shit were to hit the fan, that the people will prevail by the people bringing out their privately owned tanks, RPGs, anti-tank missiles, artillery, mortars, F-16s, helicopter gunships, surface-to-air missiles, to fight and defeat a modern army, or even part of one, on its own terms in conventional military operations? I would posit that warfare has changed a great deal since 1776, and even if the courts agreed the Second Amendment protected all of these things, it would be entirely symbolic and meaningless. Very few people could afford them, or even if they could afford them, they wouldn’t own such things in large enough numbers to make any real difference.
This is not to say that I think the Second Amendment’s purpose of enabling people to resist a criminal government is completely obsolete, just that it’s not going to happen the same way it did in 1776, only with modern weapons. Any resistance to a criminal government in the modern age will take conventional small arms, explosives, information, intelligence, and will. Small arms we have to ensure are protected under the Second Amendment. Explosives are impossible to control in such a situation, and will be available no matter what laws regulate them under a legitimate government. Intelligence and will are organizational qualities that are unrelated to arms. Hell, I would argue that the ability to tinker with model airplanes is more important to the modern concept of “militia” than knowing the principles of artillery, and knowing RF communication principles far more important than knowing logistics.
In the history of 20th century warfare, this has played out more than a few times. The Vietcong engaged in an extensive and largely successful guerrilla campaign, with only what their fighters could carry on their backs. In fact, the fatal mistake of the Vietcong was to come out of the jungle, and fight an offensive against the U.S. military on conventional terms. Militarily, Tet was a defeat for the VC, and it destroyed them as a fighting force. But Tet broke the American will, and in that sense was not a failure. It is, however, a harsh lesson what happens when a guerrilla force tries to fight a conventional army on its own terms.
What I advocate here is not an extinction of the original purpose of the Second Amendment, but to emphasise that the priority has to be on protecting conventional small arms. I don’t think whether destructive devices are protected or not really makes all that much difference in the overall scheme of things. The nature of modern warfare has not made the Second Amendment’s “defense against tyrannical government” obsolete, but it has changed the equation enough that appeals to how things were in 1776 aren’t much use in figuring out how it would be applied in a modern context.
