Under the "Brazen Conduct" rules, one could be df'ed over pretty much anything a body of elgubs, decides to!
It's been said a few times before, a JW can be DFd for anything 3 elders decide constitutes DFing, damn the scriptures and sometimes even the WT legal dept.
The gun question is interesting. Never thought about concealed carry, but back when I was growing up, living outside of a metro area, guns were basically a normal thing, even for JWs. Not necessarily protection from other humans, but for hunting, protection of livestock from other animals, and just plain ole target shooting. As the city dubs moved into the area and the city met the country, there were 'debates' about gun ownership. Most city folk didn't see the need for guns, while the country folk were defensive about hanging on to them. The rural JWs kept their guns, depsite 'counsel' otherwise. They learned to not go around bragging about it.
