Austin jury? If so, move for change of venue.
There is an organization called Second Call Defense that offers a very comprehensive legal resource that protects the gunowner involved in a lawful defense of himself against this kind of crap. Their info is at https://www.secondcalldefense.org/. And no, I don’t profit from this at all but I do enjoy their coverage.
In my county this wouldn’t have even brought to a grand jury. Change of venue and this goes away. Austin is a 3rd world Texas crap hole.
