Just looking at the beginning of the video, if he broke through the door, the father should be fine. At least hear in Texas, once they come in the home uninvited, the rules change and you can presume bad intent and act accordingly. If it were out in the yard, that would be tougher. Not sure how the laws are set up there, but I bet they are similar.
Yeah, that neighbor didn't see anything. He just saw the guy laying outside and made assumptions. I am tempted to assume he is one of those people who think if the attacker has no weapon, they should just get in a fist fight.
How made a statement that he shot through the door. Was there a hole? I can easily see that he would not see the damage to the door if the door had been forced open and then pushed closed once the guy was shot.
