A judge in Virginia has struck down a federal law prohibiting the sale of handguns to 18-, 19- and 20-year-olds, ruling the ban is an unconstitutional violation of the Second Amendment. The Justice Department will likely ask the judge to put the ruling on hold while it appeals the decision. The gun control advocacy group Everytown Law said Thursday’s ruling will put lives at risk, adding, “Not only are guns the leading cause of death for U.S. kids and teens, but research shows us that 18- to 20-year-olds commit gun homicides at triple the rate of adults 21 years and older.”
