PC §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, rob-
bery, or aggravated robbery.

PC §9.04. THREATS AS JUSTIFIABLE FORCE. The threat of force
is justified when the use of force is justified by this chapter. For pur-
poses 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 pur-
pose is limited to creating an apprehension that he will use deadly
force if necessary, does not constitute the use of deadly force.
