Joe Horn was on his own property. The criminals came from the house they had broken into and onto his property. If they would have listened to him, they would still be alive, burdening the legal systems with trials and appeals and then the wait in custody as they are shipped back to columbia (they were illegals).
Ok. They came onto his property and he says, threatened him. Now here's the thing I don't understand. Why did he shoot both in the back as they attempted to flee down the street (by Horn's own words to the dispatcher)? After all, if they threatened him, they'd have to be close enough and/or facing him to pose a threat. But they were running down towards the street,
away from him.
Exactly what did he say to them that they didn't listen to? Here is something from the OP's quote that belies what you are attempting to convey:
Horn: "Well, here it goes buddy, you hear the shotgun clicking and I'm going."
Dispatcher: "Don't go outside."
On the tape of the 911 call, the shotgun can be heard being cocked and Horn can be heard going outside and confronting someone.
"Boom! You're dead!" he shouts. A loud bang is heard, then a shotgun being cocked and fired again, and then again.
Then Horn is back on the phone:
"Get the law over here quick. I've now, get, one of them's in the front yard over there, he's down, he almost run down the street. I had no choice. They came in the front yard with me, man, I had no choice! ... Get somebody over here quick, man."
So what exactly didn't they listen to? He does not appear to have told them to stop. All he said was "Boom! You're dead!". Then the shots are heard. I am assuming from all reports that they were fleeing? Even Horn stated to the dispatcher when he returned inside his house that "he almost run down the street". So they should have listened and somehow survived when he said "Boom! You're dead!"? But then, he shot them straight away.
How exactly is someone fleeing down towards the street, with his back to Horn, a threat to Horn?
Tell me, do you think the police would have opened fire on two fleeing robbers? Or would they have attempted to chase them instead? I wonder, how many robbers do police shoot in the back as they attempt to flee and pose no danger or threat to anyone in the immediate surround?
One simple grand jury and its over. Joe Horn saved texas a bunch of tax dollars.
That says more about the society than you may want to deal with at this present time.
I guess now you can just shoot anyone you catch in the middle of a crime (no matter what that crime happens to be), as a dollar saver.
Hell, I guess I should be thankful I don't live in Texas. Otherwise my neighbour could have shot me dead after I had to break into my own house when my two year old accidentally locked me out as I was hanging out the washing. Said neighbour would have been justified in shooting me in the back a few minutes later when I was taking the rubbish out in a large rubbish bag (with my keys now in my hand).
