Why Bans on “Assault Weapons” Are Unlikely to Diminish the Deaths Caused by Mass Shootings

Eugene Volokh @ The Volokh Conspiracy:

I’m on the record as saying that bans on so-called “assault weapons” are likely constitutional (see pp. 1483-87 of this article), and several state courts have held the same under state constitutional individual right-to-bear-arms provisions before Heller. Such bans leave law-abiding citizens with ample access to other guns that are equally effective, and therefore don’t substantially burden the constitutional right. There are plausible arguments that the laws are so unlikely to do any good that they should fail “intermediate scrutiny,” even if they don’t substantially burden the right, but I’m inclined to say that courts should probably apply heightened scrutiny only to laws that do impose such a substantial burden. (For more on this general constitutional question, see also pp. 1454-61 of the article.)

But for the very same reasons, the bans seem likely to have no effect on fighting crime, because they leave criminals with ample access to other guns that are equally effective for their criminal purposes. So-called “assault weapons” are no deadlier than other weapons.

To begin with, note that assault weapons are not fully automatic weapons (which is to say machine guns). Fully automatic weapons have long been heavily regulated, and lawfully owned fully automatics are very rare, very expensive, and almost never used in crimes. Rather, assault weapons are a subset of semiautomatic weapons, generally semiautomatic handguns and rifles

Semiautomatic handguns and rifles — of which there are probably at least about 100 million in the country, and likely more — are undoubtedly extremely deadly; but the subset that is labeled “assault weapons” is not materially deadlier than the others. One way of recognizing that is looking at the definition in the 1994-2004 federal assault weapons ban; the ban lists several types of guns by name, and then provides these generic definitions:

(B) a semiautomatic rifle that has an ability to accept a detachable magazine and has at least 2 of–
(i) a folding or telescoping stock;
(ii) a pistol grip that protrudes conspicuously beneath the action of the weapon;
(iii) a bayonet mount;
(iv) a flash suppressor or threaded barrel designed to accommodate a flash suppressor; and
(v) a grenade launcher;
(C) a semiautomatic pistol that has an ability to accept a detachable magazine and has at least 2 of–
(i) an ammunition magazine that attaches to the pistol outside of the pistol grip;
(ii) a threaded barrel capable of accepting a barrel extender, flash suppressor, forward handgrip, or silencer;
(iii) a shroud that is attached to, or partially or completely encircles, the barrel and that permits the shooter to hold the firearm with the nontrigger hand without being burned;
(iv) a manufactured weight of 50 ounces or more when the pistol is unloaded; and
(v) a semiautomatic version of an automatic firearm ….

As you might gather, bayonet mounts, barrel shrouds, and the like don’t make guns materially more lethal. A grenade launcher might, but grenades themselves are already extremely heavily regulated, and in any event rifles with grenade launchers aren’t relevant to mass shootings or, to my knowledge, crime generally. Guns that fit these categories may look more dangerous; but they aren’t more dangerous.

What makes a gun deadlier? Longer barrels do, since they give the bullet more time to accelerate; that’s why rifles are deadlier than handguns, all else being equal. Accuracy does, but (for obvious reasons) no-one is trying to ban guns that are especially accurate, at least setting aside possible arguments related to high-end sniper rifles. Caliber does, because wider bullets are generally heavier bullets, but assault weapons aren’t defined by caliber size.

    Assault rifles are capable of both fully and semi automatic fire. AR-15′s LOOK like military hardward, but no nation limits its soldiers to a semi-automatice weapon as a basic tool. We have had the availability of self loading rifles since the very early 20th century around 1906. The sporting version of the Browning Automatic Rifle was available in .338 Winchester Magnum, a truly deadly caliber. The rarity of the use in crime of these look a likes is such that it would be like banning Corvettes because someone gets killed in a wreck going too fast.

  2. THOSE WHO WANT TO BAN THOSE WEAPONS
    are those who are scare by weapon carry instead of being led to feel safer by the person.
    and they are stuck with their feeling ,
    no matter what we can explain to them, they think negative on everything they do. but if a good guy take his gun to shoot a killer, they like to be the looker, not the helper.
