I don't know what their policy is, but I wouldn't be surprised if it is the same as the gun shows in Sandy. It's not actually an anti-gun policy. The reason for it is that their insurance requires this policy. Mixing mostly unloaded guns with a few loaded guns is rather a risk of a negligent discharge, so it is not a surprise.
