Editorial: It’s common sense to raise the minimum age to purchase a rifle

The back-to-back massacres at a Buffalo grocery store and a Texas elementary school have brought into sharp focus the disparity in federal gun law that forbids people younger than 18 from buying handguns but allows them to purchase semiautomatic rifles. That someone too young to buy alcohol or cigarettes is allowed to buy weapons designed for war makes no sense. If ever a loophole cried out to be closed, it is this dangerous distinction. Congress must make it a top priority in any package of reforms.
