Then you've apparently missed the shooting incidents that have occurred in such areas of airports.I damn sure don't want to be a MWAG when the Cavalry start arriving from every direction.
I've also heard that the place is considered private property, or city property, and even though CCW may be "legal" there, it's certainly frowned upon. I'm all about rights, but I'm also all about avoiding unpleasant situations whenever possible.
DIA is not private property. City property means that the CCW statute applies and preempts any municipal ordinance.
