That being said, I would get a copy of state law and show it to him. Print it out and physically give it to him. MAKE him read it. Offer to drive him to the SO or wherever it is he would have to apply, and help him with the paperwork. If at this point he refuses or admits to a reason he can't get one, then advise him of the consequences and leave it alone. It is his choice to make, not yours. If he chooses to carry illegally after being fully informed of the consequences, then he assumes the risks that go along with it.
