In Louisiana, the use of deadly force against a trespasser is generally not justified, unless the trespasser is committing a felony or poses an imminent threat of death or serious bodily harm to the person using deadly force.
Louisiana law provides a defense to a homicide charge if the defendant reasonably believes that deadly force is necessary to prevent imminent death or great bodily harm to themselves or a third person. However, the defense is not available if the defendant provoked the aggression that resulted in the use of deadly force.
Louisiana law also provides that a person is justified in using deadly force to prevent the commission of a felony in their home. However, this defense is only available if the person reasonably believes that deadly force is necessary to prevent the felony.
Therefore, in Louisiana, you cannot generally shoot someone for trespassing unless they are committing a felony or pose an imminent threat of death or serious bodily harm to you or someone else. If you use deadly force against a trespasser, you may be charged with homicide, and you will have to prove that you were justified in using deadly force.
In addition to the general rules governing the use of deadly force against trespassers, there are also some specific circumstances in which the use of deadly force may be justified. For example, Louisiana law provides that a person is justified in using deadly force to prevent the commission of aggravated arson, aggravated burglary, aggravated kidnapping, or aggravated rape.
If you are ever in a situation where you are considering using deadly force against a trespasser, you should always first try to de-escalate the situation and avoid using deadly force if possible. If you do use deadly force, you should immediately call 911 and cooperate with the police investigation.
