Most gun deaths are suicides, not homicides. That's a strong case for gun control.

A disturbingly pervasive talking point among pro-gun conservatives, like National Review's Charles C. W. Cooke, is that in debates about gun control, suicides ought not to count, or ought to count for less:

Many people, of various political persuasions, believe that suicide is ultimately just someone's choice. It may be bad, but it's not nearly as bad as homicide or death by disease, and certainly not a morally significant enough problem to justify gun control measures.

It's a common viewpoint, but it's wrong. Suicide is the terminal stage of a disease. It's a preventable death that we can, and should, prevent. And gun control is a necessary tool for doing that.

A life saved is a life saved

Obviously there's tremendous variation in particular people's ethical frameworks, but where I come from, a death is a death. The friends and family of people who've killed themselves grieve just as the friends and family of people who've been killed by others grieve. The deceased is denied years of potentially happy life whether dead by his own hand or another's.

The only way a suicide could be somehow morally "better" than a homicide is if, in some meaningful sense, it serves the interests of the person committing suicide. In all but a few cases, this isn't true. There are some rare instances where suicide may be a viable option — when terminally ill, for instance — but for the most part it's a rational failure, a cognitive bias that places way too much weight on current pain and way too little on the welfare of one's future self. Depression is a liar intent on convincing you it'll never leave. But for many people, with treatment, it does leave. If those people never got to experience that future because a disease claimed their life early, the fact that the disease in question was depression rather than cancer or heart disease hardly seems relevant. It doesn't make the outcome any less tragic. It doesn't mean the victim was asking for it.

This may feel infantilizing or insulting — who are we to say that people who commit suicide don't know what's best for them? — but believe me, it's not. I can't speak for other people who've dealt with suicidal ideation, but I can speak for myself. I've oscillated between times like now, when my baseline tendency is to feel genuinely happy and fulfilled, and times like my senior spring of college, when life felt like an impossible burden to be endured and I ignored any indications that this might change. But it did change. One night I confessed to my roommate that I'd made a plan to kill myself; he instructed me that, whether I liked it or not, I was going to start seeing a psychiatrist at least once a week. I started getting treatment, and I got better.

If I'd followed through on that plan, I would've been making a rational decision for the moment. But I'd have missed out on years of happy life and, with luck, years more to come. I more or less know what's good for me. But depression doesn't. Honoring depression's wishes doesn't do me any favors. It doesn't respect my autonomy. What does help are efforts to reduce depression's power, to place roadblocks that keep it from making decisions that will permanently harm me.

Why suicide attempts with guns are more dangerous

Limits on gun ownership, it appears, can serve as that kind of roadblock.

While high rates of gun ownership are associated with higher homicide rates, the evidence around suicide is particularly strong. For example, a recent meta-analysis, which collated studies comparing suicide and homicide victimization rates for people with and without gun access, "found strong evidence for increased odds of suicide among persons with access to firearms compared with those without access and moderate evidence for an attenuated increased odds of homicide victimization when persons with and without access to firearms were compared."

There's a popular myth that suicidal people will find a way to kill themselves no matter what, and that closing off one method (like guns) will just lead to an increase in suicides through other methods (like hanging or overdoses). But most suicides aren't committed by determined people who can't be talked out of it. They're impulsive actions that can usually be prevented by small barriers. Many survivors say they deliberated less than a day, and sometimes for only a matter of minutes, before making a suicide attempt. Ken Baldwin, who survived a jump off the Golden Gate Bridge, once told the New Yorker's Tad Friend that as he was falling, he "instantly realized that everything in my life that I’d thought was unfixable was totally fixable — except for having just jumped."

Baldwin's change of heart isn't too unusual. Ninety percent or so of people who've survived suicide attempts do not end up dying by suicide. So blocking off particularly lethal suicide methods — ones where attempts almost always lead to death — saves life. Guns are an extremely lethal suicide method. The Centers for Disease Control and Prevention found that in 2001, 85 percent of suicide attempts involving guns resulted in death, significantly above other methods. A study looking at hospital admissions for suicides and suicide attempts in Illinois found that 96 percent of firearm cases resulted in death, while only 6.7 percent of cases involving cuts and 6.5 percent of cases involving poisoning did. "In the public-health community," Leon Neyfakh wrote in an excellent piece on guns and suicide for the Boston Globe, "researchers have widely come to regard it as a basic truth that access to a gun makes it more likely that someone who wants to commit suicide actually manages to do so."

Gun control can reduce suicides

There are multiple cases of real-world gun control initiatives leading to large reductions in suicides. In the aftermath of a 1996 massacre that killed 35 people, Australia banned semi-automatic and automatic rifles and shotguns and instituted a mandatory buyback program that wound up reducing gun ownership in Australia by a fifth. An equivalent program in the US would destroy about 40 million guns.

Australian states where more guns were bought back saw greater declines in their firearm suicide rates.

Leigh & Neill 2010

A study by Andrew Leigh of Australian National University and Christine Neill of Wilfrid Laurier University looking at subsequent trends in homicides and suicides found that a buyback of that size reduces the firearm suicide rate by 74 percent. There wasn't a significant effect on non-firearm suicides. They also found an effect on firearm homicides (a 35 to 50 percent reduction), but it wasn't statistically significant because the homicide rate in Australia normally is so low. The homicide finding has been fiercely debated, but even some critics of Leigh and Neill's study conceded the effect on suicides was real. One important caveat is that handguns were already tightly controlled in Australia in 1996, which meant that long guns were being used more frequently for suicides than they are in the US. Consequently, limiting access to long guns here might have a milder effect.

A similar thing happened when the Israeli Defense Forces stopped letting troops bring their guns home over the weekend in 2006. A study by researchers with the IDF's Division of Mental Health and Sheba Medical Center found the policy change reduced suicides among IDF soldiers by 40 percent, mostly due to a drop in suicides using firearms committed over weekends, with no noticeable change in weekday suicides.

If the government has a cost-effective way to prevent thousands of deaths, it should do it. It shouldn't matter the kind of death prevented. A life saved is a life saved. Attempting to sort the worthy saved from the unworthy saved is a crass distraction from the real work at hand.
