 For NPR News in the Twin Cities, I'm Perry Finnelli. The U.S. Eighth Circuit Court of Appeals has ruled Minnesota's law banning 18 to 20-year-olds from obtaining permits to carry guns in public is unconstitutional. It affirms last year's lower court decision, saying it's a violation of the Second Amendment. State Attorney General Keith Ellison says the ruling makes it more difficult to reduce shootings and improve public safety, but the Minnesota Gun Owners Caucus called the outcome a resounding victory.
