The decedent was an idiot. He should have left the property, particularly after the warning shot, and if he’d had a valid concern on the property, he could have gotten the police to come mediate (if nothing else.)
This is *specifically* legal in Texas law. No duty to retreat.
Who said anything about retreating?
The shooter escalated the situation, discharged a firearm at someone, the shot him, he’s a murderer.
It’s clear the law of the gun is the only law in Texas.
The DA in this town is dirty, I guarantee it, even in Texas this is murder.
