We can't just kill everybody BBF, armed robbery and violent assault deserve harsh prison sentences not the death penalty.
Again, this woman did not kill in self-defence. This story was very big in the news here, after the incident she gave a long interview to a current affair show for $100,000 and she has since refused to talk to the police.
If she acted in self-defence she would have come clean to the police straight away, she was also filmed straight after the attack, she seemed to have very good recollection of the incident then and later in her TV interview. At the time she shot the armed robber, who had assaulted her, he was in the car trying to get away and clearly not posing a thread to her.
She is an armed and trained security guard, you can't tell me that she wouldn't know about shooting out car tyres instead of shooting the driver. As she fired the shot she was in the immediate vicinnity (sp?) of the car, but it was not coming or swirving towards her, in fact it's not actually clear if the robber had managed to get the car started.
