Unless the intruder is armed or is a clear and imminent threat, you cannot use deadly force.
Simply being in your house is not enough reason to shoot them.
In law school I had a crim Law professor who was a retired VA Circuit Court judge, and I recall that his take on this point was that if you shot someone entering your property it was important that the body fall on your side of the fence.
“Unless the intruder is armed or is a clear and imminent threat, you cannot use deadly force.
Simply being in your house is not enough reason to shoot them.”
This is correct. In Virginia, we have no duty to retreat, but if we do anything that even faintly resembles aggression, any self-defense plea could get shot down, so to speak. However, since the person has broken into your house already, that sort of lowers the bar for “imminent fear of great bodily injury.”
That said, you need to be able to quickly differentiate between a drunk who goes into the wrong house, a burglar who thought you weren’t home and an MS-13 home invader who wants to chop off your hands before he murders you. You can pull a gun on all three, but you can only shoot any of them if they look like they will attack.
In Texas it sure is!
You can even shoot somebody in your neighbor's house.
