A study conducted by researchers from the Johns Hopkins Center for Gun Policy and Research found that after Missouri repealed its permit-to-purchase law, which required a criminal background check prior to purchasing handguns from licensed dealers or private sellers, firearm homicides in the state increased 25%. That translated to an increase of between 49 and 68 homicides every year.
"This study provides compelling confirmation that weaknesses in firearm laws lead to deaths from gun violence," said Daniel Webster, ScD, MPH, director of the Johns Hopkins Center for Gun Policy and Research and the study's lead author. "There is strong evidence to support the idea that the repeal of Missouri's handgun purchaser licensing law contributed to dozens of additional murders in Missouri each year since the law was changed."
