I think that they had to charge him with murder as his actions looked like murder under their definition.
I think we all get it wrong when we imagine premeditation to mean ...sitting planning it the night before...rather than going getting your gun, taking it out of the holster, cocking it, walking stealthily, aiming, not firing a warning shot, pulling the trigger 4 times into a locked, enclosed space. Not allowing the intruder to surrender to escape.
His defence was PPD that he intentionally fired his gun in the mistaken belief that he was allowed to do so in order to protect his own life from attack.
They needed to show that he was aware of when and how he could use his gun
That he fired deliberately
That he used thought..
That there was no threat and therefore that the defence could not be used = murder
I think the information about it being Ms Steenkamp has somehow muddied the waters.
We all became involved in the did he love her or not debacle. Whether he did or didn't it doesn't prove or disprove domestic violence.
We were all swayed (including the judge) by his actions after the killing. Whereas many of us know that abusers are often very sorry after the act as are criminals when faced with a life in prison as are men who mistakenly kill their girlfriends?
It is utterly impossible to get your head around legally
