GunsDo gun-restriction laws help reduce gun deaths?
Researchers looked at the associations between firearm-related laws and firearm homicides, suicides, and unintentional injuries and deaths. The study is the first to explore the evidence from around the world on gun laws and gun violence to determine whether gun restrictions help reduce gun deaths. While the research did not conclusively prove that restrictions, or relaxation of laws, reduce gun deaths, the results indicate that gun violence tended to decline after countries passed new restrictions on gun purchasing and ownership.
A study by researchers at Columbia University’s Mailman School of Public Health looked at the associations between firearm-related laws and firearm homicides, suicides, and unintentional injuries and deaths. The paper is the first to explore the evidence from around the world on gun laws and gun violence to determine whether gun restrictions help reduce gun deaths. While the research did not conclusively prove that restrictions, or relaxation of laws, reduce gun deaths, the results indicate that gun violence tended to decline after countries passed new restrictions on gun purchasing and ownership. Findings are published in the February issue of Epidemiologic Reviews.
Columbia U says that the researchers reviewed the findings from 130 studies conducted from 1950 to 2014 in ten countries that had overhauled their gun law, mostly in the developed world, including the United States, Australia, and Austria. A few studies looked at gun laws in middle-income countries, including Brazil, Colombia, and South Africa.
“In most countries, we saw evidence of reduction in the firearm death rates after the enactment of firearm legislation” said Julian Santaella-Tenorio, a doctoral student in Epidemiology at Columbia University’s Mailman School and the study’s lead author.
Santaella-Tenorio and his Columbia co-authors, Professors Magdalena Cerdá and Sandro Galea, also found evidence that specific laws, such as background checks and rules on storage, reduced specific kinds of gun deaths including intimate partner homicides and firearm unintentional deaths in children, respectively.
By comparison, laws in place about carrying concealed weapons or standing your ground either had no effect on gun deaths or increased gun violence. “While our review is not proof that gun laws reduce violence, and also taking into account that for some countries there are very few papers examining firearm laws effects, we did see evidence showing an association between firearm laws and a decline in firearm homicide and suicide rates,” noted Santaella-Tenorio.
“Since we limited our review to changes in firearm policy and not ownership in general or other types of policy, the debate should not end here.”
