But that is precisely what the National Rifle Association and other opponents of firearms regulation do not want. In the absence of reliable data and data-driven policy recommendations, talk about guns inevitably lurches into the unknown, allowing abstractions, propaganda and ideology to fill the void and thwart change.
The research freeze began at a time when the C.D.C. was making strides in studying gun violence as a public health problem. Before that, the issue had been regarded mainly as a law enforcement challenge or as a problem of disparate acts by deranged offenders, an approach that remains in sync with the N.R.A. worldview.
Public health research emphasizes prevention of death, disability and injury. It focuses not only on the gun user, but on the gun, in much the same way that public health efforts to reduce motor vehicle deaths have long focused on both drivers and cars.
The goal is to understand a health threat and identify lifesaving interventions. At their most basic, gun policy recommendations would extend beyond buying and owning a gun (say, background checks and safe storage devices) to manufacturing (childproofing and other federal safety standards) and distribution (stronger antitrafficking laws), as well as educating and enlisting parents, physicians, teachers and other community leaders to talk about the risks and responsibilities of gun ownership. …
To understand and prevent motor vehicle deaths, for instance, the government tracks more than 100 variables per fatal crash, including the make, model and year of the vehicles, the speed and speed limit, the location of passengers, seat belt use and air bag deployment.
Guns deaths do not get such scrutiny. That does not mean we do not know enough to act. The evidence linking gun prevalence and violent death is strong and compelling; international comparisons are also instructive.
But we need more data to formulate, analyze and evaluate policy to focus on what works and to refine or reject what does not. How many guns are stolen? How do guns first get diverted into illegal hands? How many murderers would have passed today’s background checks? What percentage of criminal gun traces are accounted for by, say, the top 5 percent of gun dealers? How many households possess firearms: is it one-third as some surveys suggest, or one-half?
