Guns Save Lives

Button1I live in a part of the country where it’s common to see billboards and bumper stickers proclaiming that: “Guns Save Lives!”.  Recently, as I pulled into my local gun club where I practice before every season, it was emblazoned on the back bumpers of nearly half the vehicles in the lot.

I’ve long been curious about this claim, and honestly, a little dubious about its accuracy – especially given the spate of mass shootings lately.  But I also know that the media tends to sensationalize the tragic and under-report the mundane.  Cable news could do around-the-clock coverage of the murders that didn’t  happened on a given day.  But they don’t.

It’s a difficult problem, familiar to social scientists, of trying to observe or measure events that haven’t happened.  Every time there is a murder or death resulting from firearms, we have another piece of evidence linking the death to guns.  We don’t however have an easy way of knowing if or when guns helped prevent a death.  Over time, we collect more and more data (and media coverage of the latest mass shooting) that connects guns to tragic human loss while we rarely hear about situations where guns prevented tragedy – except in the movies.

There are few easy ways of collecting data on lives that aren’t lost.  But this doesn’t mean we can’t get an answer to the question: do guns save lives?  Before we get to that, let’s first examine the rationale behind the claim that they do.

At first blush it seems plausible that guns might save lives.  For instance, if an armed perpetrator entered your home intent on doing harm, it is reasonable to believe that if you had a gun, you could shoot the intruder before he got the chance to hurt anyone in your family.  In this case, we see how guns could save lives.  We see this scenario played out on television and in the movies all the time.  The hero, armed with a gun shoots the bad guy and saves the innocent people (his family, his girlfriend, or his country). It’s a formula seen so often the popular culture that it may seem like common sense: guns save lives.

Another line of the argument rests on the notion that shots don’t have to be fired for guns to save lives.  It’s a logic that goes like this: if a criminal feared that owners of the home he was about to invade were armed and might shoot him, he may be deterred from trying to enter the house in the first place.  This deterrence idea may be the biggest thrust behind the idea that guns save lives.  Those who believe this feel that more guns save more lives since the more people who are armed, the greater the overall deterrent effect.  Played out to its logical end, if everyone in a society had a gun, the risk to would-be criminals would be very high.   The greater risk would then lead to a reduction in crime and presumably fewer deaths. Guns, therefore, could be considered a critical element in saving lives.

But to others, the claim that guns save lives sounds absurd.  Guns are tools designed specifically to kill. How could a lethal weapon, particularly if it is widely available, lead to anything but more deaths? Stories appear in the news every day describing someone being shot and killed — often accidentally, more often murdered.  In the last few years we have seen tragic shooting deaths at a theater in Colorado, a Sikh Temple in Wisconsin, and a school in Newton Connecticut (and many others).

It is hard to imagine a deranged person exacting a similar toll armed with only his fists or a knife, or a slingshot.

Folks who have a hard time seeing guns as life-savers can point to episodes like these where an unstable individual is able to acquire guns and commit atrocities.  This is a compelling counter argument to the claim that guns saves lives.  Without guns these deranged souls would have much less lethal means at their disposal.  Guns make it more likely that lives would be lost during such violent outbursts. It is hard to imagine a deranged person exacting a similar toll armed with only his fists or a knife, or a slingshot.

So is the claim true? If guns truly save lives, we should be able to find evidence to back it up.  While it may be difficult to observe “non-events” it is still possible to assess by using comparisons between countries or states.

For example, in 2009 there were 9,146 murders in the U.S. committed with firearms.  In the U.K. there were only 39.  The US population is five times larger than the UK so that accounts for some of the variation. But the size of the population comes nowhere close to explaining the fact that the firearm homicide rate in the US is more than 230 times greater. If we adjusted the rate to reflect the UK’s smaller population, there would only have been about 200 murders by firearms in the U.S that year.

A key difference between these two countries is the number of guns per capita.  In the US there are nearly 90 guns per 100 residents (the most in the world) while the number in England, Wales and Scotland is around 6. So the belief that more guns in the hands of more people saves livesarizona guns save lives is undermined by this comparison.  If the believers in deterrence were right, we should see far more gun murders in the UK than the US when in fact the opposite is true.

We can also do useful comparisons between states within the US. Researchers find that states with high levels of gun ownership have higher incidence of homicide generally.  Murder rates in states in the top quartile in gun ownership were 114% higher than those in the bottom quartile.   And a study from the Violence Policy Center found that the top five states in gun ownership had significantly higher firearm related homicides than the bottom five states.  In fact the gun murder rates were four to ten times higher in states with the highest gun ownership compared to those with the lowest.

Again, these comparisons challenge the claim that guns save lives.  The evidence suggests otherwise. And this is just gun related murders.  What about other gun deaths like accidents and suicides?  If we are going to be making a fair evaluation of the claim that guns saves lives, these unfortunate events have to be considered.

“Two of every three gun-related deaths each year in the US is self-inflicted”



In 2010 there were more than 19,000 suicides by firearms.  That means roughly two of every three of the 30,000 gun-related deaths each year in the US is self-inflicted.   In fact, researchers have pointed to the suicide problem as the forgotten public health epidemic noting that the focus on gun murders obscures the dangers of having guns that are easily accessible at a time of personal crisis, when the likelihood of following through is higher.  The ease of access to guns — particularly in those households that own them — almost certainly contributes to the high suicide rate.

There are many issues surrounding guns and gun control that remain difficult to resolve.  Do we still have, or need, the right to bear arms?  If we decide to implement more rigid gun control, how would we get all the guns out the the hands of bad people?  These are fair questions and I don’t have an answer to them.  However, I am certain that guns do not “save lives.”

Whether you are an avid hunter, a gun collector, or a staunch defender of the Second Amendment doesn’t change the fact that guns are more likely to take life than save it.  Nor does it change the fact that having a gun in your home increases the chances that the lost life will be yours — or someone close to you.

This does not mean that a gun has never played a role in saving a life.  Most certainly this has happened.  But the claim being made on those billboards and bumper stickers is not: “Guns might occasionally save lives” .  Those rare and unknowable cases don’t come close to offsetting the wide-spread and persistent pattern of lost life attributable to guns.  Where there are more guns, there is almost always more gun-related death. The notion that guns save lives may be an article of faith for many, but it is not one based on the facts.
