Tab you are seriously reaching on this one. Have most of us here broken the law and not even known it? Probably. Would they be cases that a FEDERAL prosecutor would take the time to file charges? Highly doubtful. You are talking a bout laws written 80 years as a knee jerk reaction to an immediate problem. They are irrelevant now and I would bet that most prosecutors don't even know what they are.
I'm with 2How on this. If you have gone through the hoops and gotten your CCW, that should be your security check. Building, AIRPORTS, and anywhere else. You have already been more thoroughly screened than the other sheep going through the metal detector.
And YES I think you should be able to carry on a plane. Get rid of the stupid air marshals, and the TSA. (How much would THAT cut from the budget?

) And let's get back to traveling like responsible CITIZENS instead of being herded like little kids in day care!
I am surprised that you are so afraid of someone with a CCW. Most are better trained and more responsible with a weapon than the cops.
