But there is a more fundamental problem with the idea that guns actually protect the hearth and home. Guns rarely get used that way. In the 1990s, a team headed by Arthur Kellermann of Emory University looked at all injuries involving guns kept in the home in Memphis, Seattle and Galveston, Tex. They found that these weapons were fired far more often in accidents, criminal assaults, homicides or suicide attempts than in self-defense. For every instance in which a gun in the home was shot in self-defense, there were seven criminal assaults or homicides, four accidental shootings, and 11 attempted or successful suicides.
The cost-benefit balance of having a gun in the home is especially negative for women, according to a 2011 review by David Hemenway, director of the Harvard Injury Control Research Center. Far from making women safer, a gun in the home is “a particularly strong risk factor” for female homicides and the intimidation of women.
In domestic violence situations, the risk of homicide for women increased eightfold when the abuser had access to firearms, according to a study published in The American Journal of Public Health in 2003. Further, there was “no clear evidence” that victims’ access to a gun reduced their risk of being killed. Another 2003 study, by Douglas Wiebe of the University of Pennsylvania, found that females living with a gun in the home were 2.7 times more likely to be murdered than females with no gun at home.
Regulating guns, on the other hand, can reduce that risk. An analysis by Mayors Against Illegal Guns found that in states that required a background check for every handgun sale, women were killed by intimate partners at a much lower rate. Senator Patrick Leahy, the Judiciary Committee chairman, has used this fact to press the case for universal background checks, to make sure that domestic abusers legally prohibited from having guns cannot get them.
As for the children whose safety Ms. Trotter professes to be so concerned about, guns in the home greatly increase the risk of youth suicides. That is why the American Academy of Pediatrics has long urged parents to remove guns from their homes.
