Using “deadly force”
In on a post on Looting in Houston, Prof. Eugene Volokh writes, “whatever the practical or moral merits of shooting looters, I think it’s surely morally laudable to warn looters that Texas law generally authorizes people to kill thieves to protect or recover their own property (setting aside the situation where the target took the property in order to survive).” The law also permits people to use deadly force to protect others’ property under similar circumstances.
It’s worth noting that Indiana Code 35-41-3-2 has somewhat similar provisions.
(a) A person is justified in using reasonable force against another person to protect the person or a third person from what the person reasonably believes to be the imminent use of unlawful force. However, a person is justified in using deadly force only if the person reasonably believes that that force is necessary to prevent serious bodily injury to the person or a third person or the commission of a forcible felony. No person in this state shall be placed in legal jeopardy of any kind whatsoever for protecting the person or a third person by reasonable means necessary.
(b) A person is justified in using reasonable force, including deadly force, against another person if the person reasonably believes that the force is necessary to prevent or terminate the other person’s unlawful entry of or attack on the person’s dwelling or curtilage.
(c) With respect to property other than a dwelling or curtilage, a person is justified in using reasonable force against another person if the person reasonably believes that the force is necessary to immediately prevent or terminate the other person’s trespass on or criminal interference with property lawfully in the person’s possession, lawfully in possession of a member of the person’s immediate family, or belonging to a person whose property the person has authority to protect. However, a person is not justified in using deadly force unless that force is justified under subsection (a).
Therefore even the threat of injury or felony can justify deadly force. Force is not defined by the result but by the foreseeability determined by reasonable belief.
