Several of the City Council members are gun advocates, and by motion they called to remove the 'exception' from the initial amendment. This would simply enact legislation mirroring the new state law. Last night was still only the first reading, so we still have two more to go before the 'exception' is dead. Even so, the lingering possibility that another run at controlling gun rights at the city level looms overhead, so we will continue to keep an eye on this.
WyGO's director made clear that any attempt to regulate firearms at the city level, against the state preemption, would result in lawsuit. The mayor noted this statement. After a unanimous vote by the council, the first reading accepted the 'mirroring' of the state law within the city, leaving out the exception for government buildings.
Hope this sheds some light on this round of city-level attempts to legislate something that is simply outside of their scope.
