So I saw a sign at the collectors west gun and knife show at the fairgrounds last weekend that said "No loaded firearms, no exception except law enforcement." Is this intended for people bringing firearms for trade? (I know last year back East someone got shot when a shotgun went off while a guy was opening his rifle bag.) Or are they asking people with their CPL to unload their carry pieces before entering? If so, what are the consequences of ignoring this sign? I found no actual legislation regarding this.
