Ok, then . . . was this man at home, in his vehicle, or at his place of employment?
I point you to the story in Houston 2 years ago about the man who heard his neighbors house being robbed. He stated on the 911 call that he was going to stop them, he killed them in his neighbors home and is sitting at home right now watching TV.
Again with respect.
Last year a CCW permit holder was walking his dog in a park in Terrell Texas when a few punks tried to rob him. I believe he killed one thug and wounded the other. Not at home, work, and was no where near his vehicle. He was not charged.
