Another Study Torpedoes Defensive Gun Use

A recent study published in The Journal of Preventative Medicine offers new support for the argument that owning a gun does not make you safer. The study, led by David Hemenway, Ph.D., of the Harvard T.H. Chan School of Public Health, examines data from the National Crime Victimization Survey — an annual survey of 90,000 households — and shows not only that so-called “defensive gun use” (DGU) rarely protects a person from harm, but also that such incidents are much more rare than gun advocates claim.

Contrary to what many gun advocates argue, the National Crime Victimization Survey (NCVS) data reveals that having a gun provides no statistically significant benefit to a would-be victim during a criminal confrontation. The study found that in incidents where a victim used a gun in self-defense, the likelihood of suffering an injury was 10.9 percent. Had the victim taken no action at all, the risk of injury was virtually identical: 11 percent. Having a gun also didn’t reduce the likelihood of losing property: 38.5 percent of those who used a gun in self-defense had property taken from them, compared to 34.9 percent of victims who used another type of weapon, such as a knife or baseball bat.

What’s more, the study found that while the likelihood of injury after brandishing a firearm was reduced to 4.1 percent, the injury rate after those defensive gun uses was similar to using any other weapon (5.3 percent), and was still greater than if the person had run away or hid (2.4 percent) or called the police (2.2 percent).
