I wonder where one might find that in writing, as in printable for a reference?

I’ve flown a bit with my match guns, and procedures vary *wildly* from airport to airport.

Last year @ Raleigh-Durham, the airport staff wanted me to hand *them* the keys to my case, while *they* took it behind closed doors to be inspected. Obviously, I refused, politely but adamantly. They weren’t happy, but arranged for another airport personnel to escort me back past all the “Authorized Personnel Only” doors, dodging (literally) baggage cars ferrying to and from planes, to a fellow in a corner with a stationary scanning machine. Once the cased fire-arm passed (never opened), we went *back* out to the check-in area and then progressed normally.

All the while, I was thinking to myself that no way, no how, would it have been a good idea to let some random airport person (not even TSA, as far as I could tell) have the keys to my gun case… but they acted like it was standard practice there.
