I'm not sure what the issue is.
(I'm not covertly criticizing; I just don't know. Plus, it seems this thread is a continuation of something earlier, so maybe I've missed something important.)
Inmy mind, I'm thinking that if something is not made illegal by law, then it is presumed to be legal.
If you think about it, there would be no real reason to define open carry. Carry has long been legal and constitutionally protected, depending on jurisdiction. I'm thinking the only reason anybody would bother to define something would be if it were illegal or regulated somewhere in the statutes or ordinances.
If it has never been illegal or regulated in your state, there may not be a definition.
