Texas Penal Code §9.42 does contain the following language:
" A person is justified using deadly force against another to protect land or tangible, movable property:
....(B) to prevent the other who is fleeing immediately after committing burglary, robberty, aggravated robbery, or theft during the nighttime from escaping with the property, and
(3) he reasonably believes that:
(A) the land or property cannot be protected or recovered by any other means; or
(B) the use of force other than deadly force to protect or recover the land or property would expose the actor or another to a substantial risk of death or serious bodily injury."
So technically you can shoot if they are escaping with your property.
Again, there's the law, and living with the consequences. You can probably count on being prosecuted unless there's a smart grand jury or sympathetic prosecutor. You'll be making this argument as an affirmative defense at trial, likely as not.
