Johns Hopkins Finds Repeal of Missouri's Background Check Law Associated with Increase in State's Murders

Missouri's 2007 repeal of its permit-to-purchase (PTP) handgun law, which required all handgun purchasers to obtain a license verifying that they have passed a background check, contributed to a 16 percent increase in Missouri's murder rate, according to a new study from researchers with the Johns Hopkins Center for Gun Policy and Research. The study, to be published in a forthcoming issue of Journal of Urban Health, finds that the law's repeal was associated with an additional 55 to 63 murders per year in Missouri between 2008 and 2012.
