This does not look like a "good" shoot to me, if there is such as thing. The shooter initiated the incident by standing beside the car and saying whatever he was saying. In Texas, that's a very important element if you decide to use deadly force. You can't start some shit and then shoot someone. The other piece is that it appears the victim started to back away before the shooter drew his gun. Hopefully, whatever needs to happen to get this guy charged, & in court, happens and a jury of his peers can decide his fate.
