ecent 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.
A 2014 Gallup poll suggests that Americans increasingly perceive owning firearms as an effective means of self-defense — having a gun makes one less likely to become a victim of a crime. But as Hemenway’s study demonstrates, this belief is not supported by crime statistics. 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.
