Silencing the Science on Gun Research
On December 14, a 20-year-old Connecticut man shot and killed his mother in the home they shared. Then, armed with 3 of his mother’s guns, he shot his way into a nearby school, where he killed 6 additional adults and 20 first-grade children. Most of those who died were shot repeatedly at close range. Soon thereafter, the killer shot himself. This ended the carnage but greatly diminished the prospects that anyone will ever know why he chose to commit such horrible acts.
In body count, this incident in Newtown ranks second among US mass shootings. It follows recent mass shootings in a shopping mall in Oregon, a movie theater in Colorado, a Sikh temple in Wisconsin, and a business in Minnesota. These join a growing list of mass killings in such varied places as a high school, a college campus, a congressional constituent meeting, a day trader’s offices, and a military base. But because this time the killer’s target was an elementary school, and many of his victims were young children, this incident shook a nation some thought was inured to gun violence.
As shock and grief give way to anger, the urge to act is powerful. But beyond helping the survivors deal with their grief and consequences of this horror, what can the medical and public health community do? What actions can the nation take to prevent more such acts from happening, or at least limit their severity? More broadly, what can be done to reduce the number of US residents who die each year from firearms, currently more than 31 000 annually?1
The answers are undoubtedly complex and at this point, only partly known. For gun violence, particularly mass killings such as that in Newtown, to occur, intent and means must converge at a particular time and place. Decades of research have been devoted to understanding the factors that lead some people to commit violence against themselves or others. Substantially less has been done to understand how easy access to firearms mitigates or amplifies both the likelihood and consequences of these acts.
For example, background checks have an effect on inappropriate procurement of guns from licensed dealers, but private gun sales require no background check. Laws mandating a minimum age for gun ownership reduce gun fatalities, but firearms still pass easily from legal owners to juveniles and other legally proscribed individuals, such as felons or persons with mental illness. Because ready access to guns in the home increases, rather than reduces, a family’s risk of homicide in the home, safe storage of guns might save lives.2 Nevertheless, many gun owners, including gun-owning parents, still keep at least one firearm loaded and readily available for self-defense.3
In 2011, Florida’s legislature passed and Governor Scott signed HB 155, which subjects the state’s health care practitioners to possible sanctions, including loss of license, if they discuss or record information about firearm safety that a medical board later determines was not ‘relevant’ or was ‘unnecessarily harassing.’ A US district judge has since issued a preliminary injunction to block enforcement of this law, but the matter is still in litigation. Similar bills have been proposed in 7 other states.
