Let's look at TPC 9.31Soccerdad1995 wrote:At what point could you legally display your weapons, and at what point could you legally open fire? Do you need to wait until the mob has reached your vehicle? Until you are surrounded? Or can you take action before that time?
and 9.32[A] person is justified in using force against another when and to the degree the actor reasonably believes the force is immediately necessary to protect the actor against the other's use or attempted use of unlawful force.
Those sections go on to explain in which instances where you are automatically given the presumption that your use of force/deadly force is justified, but in my non-lawyer opinion (law types feel free to correct me) is that you still have the defense that you reasonably believed it was necessary to prevent or end the attacker's use of force/deadly force.Sec. 9.32. DEADLY FORCE IN DEFENSE OF PERSON. (a) A person is justified in using deadly force against another:
(1) if the actor would be justified in using force against the other under Section 9.31; and
(2) when and to the degree the actor reasonably believes the deadly force is immediately necessary:
(A) to protect the actor against the other's use or attempted use of unlawful deadly force; or
(B) to prevent the other's imminent commission of aggravated kidnapping, murder, sexual assault, aggravated sexual assault, robbery, or aggravated robbery.
Also according to 9.04, threatening to use deadly force if necessary is not considered deadly force.
Sec. 9.04. THREATS AS JUSTIFIABLE FORCE. The threat of force is justified when the use of force is justified by this chapter. For purposes of this section, a threat to cause death or serious bodily injury by the production of a weapon or otherwise, as long as the actor's purpose is limited to creating an apprehension that he will use deadly force if necessary, does not constitute the use of deadly force.
