Some years before he moved to Montana, I was talking to Ken Hackathorn about his traveling to do gun instruction.
He told me how on one trip when he arrived at the airport with his guns, and TSA was inspecting them, one agent raised objection to the guns, but another agent said "No, he has them cased and they are OK to go." At which point the first lady agent said, "Yes, but they are black!"
Any gun could be called an "assault" weapon since they could be used to assault, and being so labeled could perhaps be made to fall within a "prohibited" category.
