Then you should follow whatever you think is required. The fact remains, you aren't even required to have a copy of the Forms 1- Infinity in your possession and you are only required to show it upon demand to an ATF agent.
Showing it to local LE if asked is probably a good idea, although not a guarantee you won't be arrested. The TSA idiots certainly don't know what it is and most local LE don't have a clue either.
