Private organizations offering events at public parks in Tennessee cannot ban legally carried guns at the venue. This according to an opinion issued by the Attorney General Herbert Slatery. The ruling seems to overturn a weapons ban at Nashville’s new Ascend Amphitheater, which banned guns at it’s 1st concert last night. The Riverfront Park is owned by Metro Nashville but private groups will sponsor many events. Lawmakers passed legislation that lifts gun bans imposed by many cities in public parks. The law overturned weapons bands imposed by Manchester and Murfreesboro along with about 70 other municipal and county governments in Tennessee. A Metro Nashville lawyers says he will challenge Slatery’s opinion.
