GUNSSafe Storage and Minimum Age Gun Laws Would Curb Violence, Study Says

A new report found that minimum age requirements for purchasing firearms appear to reduce suicides among young people. Additionally, it indicated that laws aimed at reducing children’s access to stored guns may also lower rates of firearm suicides, unintentional shootings and firearm homicides among youth. Layering a variety of firearm policies might work best to prevent deaths, researchers say.

The deadliest school shooting in Georgia history occurred earlier this month when a 14-year-old gunman, armed with a military-style rifle, killed two students and two teachers and injured nine others at Apalachee High School in Winder, a city about an hour northeast of Atlanta.

And on Sunday, former President Donald Trump was the target of what the FBI described as an apparent assassination attempt at his golf club in West Palm Beach, Florida — just nine weeks after surviving another attempt on his life.

Gun policy has been a topic of debate in America for decades, and its prominence has increased as gun-related deaths and mass shootings have risen nearly every year since 2014, according to the Gun Violence Archive, a nonprofit that tracks gun violence in the United States.

Many Americans despair of ever taming the epidemic, but a new report says certain laws can make a difference.

The report, published in July by Rand, a nonprofit, nonpartisan research organization, found that minimum age requirements for purchasing firearms appear to reduce suicides among young people. Additionally, it indicated that laws aimed at reducing children’s access to stored guns may also lower rates of firearm suicides, unintentional shootings and firearm homicides among youth.

This is the fourth time that Rand has released the report, “The Science of Gun Policy,” since 2018. Earlier editions examined the effectiveness of other gun regulations, such as background checks and concealed carry laws, and their impact on outcomes such as crime and suicide.

The “Science of Gun Policy” report examines laws individually. But a separate Rand study published in July, this one in the peer-reviewed journal JAMA Network Open, explores the combined effects of multiple state-level gun laws, including background checks, minimum age requirements, waiting periods, child access restrictions, concealed carry and stand your ground laws.

“We should try to be looking at policies jointly, because individually, each one may have a small effect, but if you start layering these restrictions on each other, they may start to really make a difference,” Terry Schell, the study’s lead author and a senior behavioral scientist at Rand, told Stateline. “That is worth thinking about.”

The study found that states with the most restrictive gun policies had a 20% lower firearm mortality rate compared with states with the most permissive laws, suggesting that comprehensive policy approaches may be more effective than individual policies in curbing gun violence.
