A huge international study of gun control finds strong evidence that it actually works
By Zack Beauchamp
What do we really know about the research on whether gun restrictions help reduce gun deaths? Even for PhDs, this is a difficult question. There's been a mountain of research on the subject, but these dozens of studies conducted over many years and in many different countries reach a broad and sometimes contradictory range of conclusions. It's hard to know what it really tells us, taken together, about whether gun laws can reduce gun violence.
A just-released study, published in the February issue of Epidemiological Reviews, seeks to resolve this problem. It systematically reviewed the evidence from around the world on gun laws and gun violence, looking to see if the best studies come to similar conclusions. It is the first such study to look at the international research in this way.
The authors are careful to note that their findings do not conclusively prove that gun restrictions reduce gun deaths. However, they did find a compelling trend whereby new restrictions on gun purchasing and ownership tended to be followed by a decline in gun deaths.
"Across countries, instead of seeing an increase in the homicide rate, we saw a reduction," Julian Santaella-Tenorio, a doctoral student in epidemiology at Columbia University and the study's lead author, told me.
