And you cited the proposed bill, not the final statute
PENAL CODE CHAPTER 9. JUSTIFICATION EXCLUDING CRIMINAL RESPONSIBILITY
So let’s look and bold the relevant parts:
Sec. 9.31. SELF-DEFENSE. (a) Except as provided in Subsection (b), 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. The actor's belief that the force was immediately necessary as described by this subsection is presumed to be reasonable if the actor:
(1) knew or had reason to believe that the person against whom the force was used:
(A) unlawfully and with force entered, or was attempting to enter unlawfully and with force, the actor's occupied habitation, vehicle, or place of business or employment;
(B) unlawfully and with force removed, or was attempting to remove unlawfully and with force, the actor from the actor's habitation, vehicle, or place of business or employment; or
(C) was committing or attempting to commit aggravated kidnapping, murder, sexual assault, aggravated sexual assault, robbery, or aggravated robbery;
(2) did not provoke the person against whom the force was used; and
(3) was not otherwise engaged in criminal activity, other than a Class C misdemeanor that is a violation of a law or ordinance regulating traffic at the time the force was used.
(b)
The use of force against another is not justified:
(1) in response to verbal provocation alone;
Except the door was unlocked. She attempted to put her key in the door and realized it was unlocked. So she could NOT reasonably believe he entered with force, there was no evidence he was vomiting a crime (he was sitting on the couch with the tv on) and he made no provocation. So none of the factors fit, and she had the ability to call for backup before engaging.
Texas law does not recognize voluntary manslaughter. She was not criminally negligent (crime of criminally negligent homicides) nor was she reckless (manslaughter) as both of those require lack of intent.
It did not rise to the level of capital murder, so murder is the only charge applicable.
She was not in her own property...she was trespassing, and self defense does not apply.
Her only defense was a mistake of fact...that she reasonably believed she was in her own apartment...and also that she reasonably believed she was in immediate danger and deadly force was the best response. She failed to support that in her testimony.
And note that my posts do not need to mention race or political affiliation to be true.
