Bump Stocks

Listening to audio from the shooting in Las Vegas, many people concluded the gunman had used automatic weapons. However, it turned out that he had used legally purchased semi-automatic rifles that had been legally modified with bump stocks. Normal semi-automatic weapons fire as fast as the user can pull the trigger, but only one shot is fired per trigger pull. A bump stock does not change the way the gun fires, rather it speeds up the rate of fire by using the recoil of the gun to push the trigger against the user’s trigger finger. If a person could manually pull the trigger as fast, the result would be the same—but such rapid pull is not something people are generally capable of doing.

While a bump stock boosts the rate of fire of a semiautomatic weapon, it does so at the cost of accuracy—the weapon bumping makes it considerably harder to aim properly. When used at a gun range, the usual point of the bump stock is to have the thrill of firing an “automatic” weapon and, as such, accuracy is not a major concern. This high rate of inaccurate fire also allows such a weapon to be devastating when it is fired into a crowd of people—the high volume of fire means that people are likely to be hit. In the case of Las Vegas, the shooter had a dense crowd to fire into and accuracy was irrelevant—he was clearly not after a specific target but rather endeavoring to maximize death and injury. For this, the bump stock was very effective. While bump stocks do not seem to have been employed in other mass shootings, the fact that they were used in such a horrific event means that the attention of the media, pundits and politicians is upon them. And, of course, the attention of bloggers. As would be suspected, those on the left are calling for legislation against bump stocks. Interestingly, some conservatives are also willing to consider the matter. Somewhat shockingly, even the NRA seems willing to discuss the subject.

Before thinking that the NRA is acting out of character, it must be noted that while the NRA did seem to endorse new regulations on bump stocks, it opposes new legislation. Somewhat ironically, the NRA also blamed Obama for allowing the sale of bump stocks. Unsurprisingly, the NRA also made the stock assertions that more gun control would do nothing to prevent attacks and that such shooting are due to the mental illness of the shooter. Even the NRA’s endorsement of another review of bump stocks by the ATF amounts to little: the ATF already reviewed the bump stock and determined that it falls within the law. Roughly put, the bump stock does not modify a gun to be fully-automatic, it merely enables an increase in the rate of fire. As such, any change in the regulation of bump stocks would presumably require legislation—something the NRA opposes. This does, of course, raise the question of whether bump stocks should be controlled or even banned.

The easy and obvious argument for legislation controlling bump stocks is that the harm argument: the use of a bump stock allows a semi-automatic weapon to fire at near automatic rates, thus enabling the sort of carnage that occurred in Las Vegas. Bump stocks are clearly not needed for hunting and have dubious value for self-defense. In fact, the inaccuracy and high rate of fire would make them a danger to any innocents in the area where they might be used in self-defense. Their main legitimate use, like that of beer, is to have fun. However, allowing such a dangerous modification to be legal just so that people can have some fun at the range would be comparable to allowing something else that is deadly, but fun for some, to be uncontrolled. As such, controlling bump stocks is both sensible and ethical. Naturally, this principle would need to be applied consistently to anything that is enjoyable yet potentially deadly.

An argument against new legislation is that this move would pave the way for more gun legislation and this road leads to the Second Amendment being eroded or even repealed. This threat to a basic constitutional right is unacceptable, so the bump stocks should remain as they are. The counter to this is that it is clearly possible to have gun legislation while also maintaining constitutional rights—after all, automatic weapons are banned and this is consistent with gun rights. Another counter is to see this path towards more control as a good thing—a feature rather than a bug.

Another concern is that the creation of legislation in the heat of the moment and directed against some aspect of a terrible event could easily result in bad laws. Going along with this is the concern about the actual risk posed by bump stocks. While they do allow a higher rate of fire, there is the question of how much of a difference they make over unmodified semi-automatic weapons. After all, mass shootings have had high casualty rates when the attacker used only semi-automatic weapons. If the bump stocks do not make a significant difference, then legislation would be unnecessary. Since having laws that are ineffective is a bad idea, these bump stocks should not be controlled.

It can be replied that sensible legislation can be crafted if it turns out that a rational and calm analysis of bump stocks shows that they do make a significant difference regarding mass shootings. This principle would, of course, need to be applied consistently—that weapons and weapon modifications that make mass shootings more lethal should be better controlled. It needs to be noted that this principle could be extended to all firearms—but to assume that this must happen would be to fall into the slippery slope fallacy.
