Not sure what you mean by "leeway".
Holding off on the draw until he declared physical intention to harm? Perhaps she should have said excuse me Sir, do wish to do me harm today or perhaps rape me in front of my child?
Normal people do not go around exposing themselves to women or anyone. To behave in this manner clearly shows that he at least has a mental problem, and at most anything could happen. So she played it safe and drew on him. He could have jumped on her in an instant.
Are we trying to advocate this type of behavior as somehow being ok because of what John law may do, or some silly continuum of force ladder? With a woman? That's preposterous and would create loopholes for pervs. Continuum of force is for men.
