Did the defense go over the castle doctrine well? Because the state is discussing self defense beautifully and while the Castle Doctrine is a form of self defense what I've read (and I am NOT versed in TX law), indicate that just the presence of an intruder signifies an immediate threat. Meaning it doesn't necessitate a person rushing at the person who uses self defense, or brandishing a weapon, etc. It doesn't have to be last resort. You don;t have to retreat or find another option with the Castle Doctrine from what I can tell.
