Operator: You're going to get yourself shot if you go outside that house with the gun."
Caller: "You wanna make a bet? I'm going to kill them."

That's not going to play well with a jury either. At the very least this guy's going to have some really big legal bills.

Again, depends who’s on the jury. The operator said HE was going to get shot, he said “I don’t think so”, in his own words of course. Besides, if there is a law in Texas that covers defending a neighbors property and he was given the task to defend the neighbors property AND knew the law, it may not be such a long shot.
