Help me on this one. What exactly does this do for OC that we already don't have? Please forgive my lack of comprehension on this thread. Thanks.
How about this hypothetical scenario. If we had lost, the city of Ferndale, who has tried in the past to ban guns from city hall and lost, could create a "governmental building authority" then sell city hall to them for $1 with the stipulation that they can use it rent free for all time. Then the "governmental building authority" could legally ban all guns, concealed or open, because "authorities" were not specifically named in the list of governmental units that were preempted.
Since we won, it can now also be used as stepping stone to get more places opened up to us to carry in. For instance, The Cobo Center in Detroit is owned by "Detroit Regional Convention Facility Authority", which was set up by the city of Detroit, and they don't allow firearms for their events. Since they are publicly owned they could be sued to force them to allow the carrying of firearms.
