If you are a gunseller, and someone is buying a gun from you, and they say "I'm going to use this gun to kill my neighbor" or "I'm going to use this gun to kill myself", what kind of legal obligation does the gunseller have? Do they legally still have to sell the gun to the person? Do the legally have to NOT sell the gun to the person?
