A nationwide study led by Boston University researchers that analyzes the impact of gun-control laws in the US has found that just 9 of 25 state laws are effective in reducing firearm deaths.
The research, published in The Lancet, suggests that three laws implemented in some states could reduce gun deaths by more than 80 percent if they were implemented nationwide. Laws requiring firearm identification through ballistic imprinting or microstamping were found to reduce the projected mortality risk by 84 percent; ammunition background checks by 82 percent; and universal background checks for all gun purchases by 61 percent.
