I’m guessing here, but I suspect them folks in charge at Aslantepe Mound, Malatya had laws limiting assault swords and who could own them. /S
That is how you hold power, doncha know.
It has been commonplace throughout history for rulers to forbid the common people from possessing swords or other weapons used by the warriors. And that was for exactly the reason that you mentioned.
Good swords and daggers are most definitely "assault weapons". They are also costly - as much as firearms are today.
Our second amendment "rights" are an historical anomaly. Governments of all types and in all times usually refuse to be restrained by such ideas.
