Texas Penal code specifically uses the term "habitation", not "property" when discussing the use of deadly force. If some jackass is shooting at strangers who wandered onto his property, he's committing a felony.
See Texas Penal Code §9.31 (castle doctrine as it relates to trespass and non-deadly force) and §9.32 (castle doctrine as it relates to habitation and deadly force).
