@Dragonlovermom:
I think the murder charge is accurate here. First and foremost the teens should not have broken into his home. This man had been burglarized previously (perhaps not by them) and he was tired of it. When he heard the glass break and subsequently confronted the first kid (Nick) I have no problem with him shooting him. Had he killed him with the first blast that would have been fine as far as I'm concerned. The issue for me comes with the second shot because Nick was no longer a continuing threat.
In regards to the female the same thing applies. Have no problem with shooting her either. However she did not initially die. According to the transcript he tells her she's going to die and calls her a *****, then he blast her again.
In my view there's a difference between killing to protect ones home and vengeance. This crossed into vengeance.
