"..to the degree the actor reasonably believes the force is immediately necessary.."
I didn't know his cell phone number, and he obviously wasn't listening or observing anything I was doing. There was no other way to immediately make him cease his actions. Abd, take note the law doesn't say "one reasonably believes." It specifically says "the actor."
No, it would not. And, I didn't care if he heard me. He was trespassing as long as he was on the property. The only way he would "cease his actions" is if he left the property. I would have had no way of guaranteeing this, other than to observe him leaving the property. Which, by the time I got to his location, he could have gone anywhere. Perhaps, to even hide and ambush me. I've been shot at before on my own property.
You seem to be ignoring the fact that I live here, and been a landowner here for decades. I've seen these cases go down. The DA rarely touches them, and if the offender/trespasser makes the mistake of being armed, or decides to carry out their shenanigans "under cover of darkness" it gets even worse for them. I believe the DA and local judges stay away from these cases is because the landowner usually prevails. Organizations like the Texas Cattleman's Association throw a lot money and resources to ranchers and farmers in this state to protect and defend them from being run over by zealous prosecutors looking to protect criminals.
