Hi Joni... welcome to the Pistorius case thread
As snippets are revealed by testimony, speculation about the events of the night of the shooting flares in the media, but back at Court little has changed overall.
We still have the initial question of "Is OP lying?" I am 50/50 on that still. I can see many people are surer than 50%, but "beyond reasonable doubt" requires a lot more than just "more than 50% convinced"
Anyway.... the initial burden on the State is to disprove OP's version and claim (in his mind) he was acting in self defense.
If State can disprove OP's claim... and the Judge regards that OP is lying.. then OP should be found guilty of Premeditated Murder (or SA equivalent) because in that case he most likely assaulted, and threatened and chased Reeva into the toilet, and shot 4 times knowing she was behind the door. Quite horrendous and deserving of a lengthy sentence (quite likely DP in some US States).
However... if the State fall short in THEIR BURDEN to disprove OP's claim, then the Judge has to accept that OP believed the whole "Intruder" scenario, genuinely. Any evaluation of crimes committed by OP will have to be evaluated from the point of view of there BEING an intruder, and how OP's actions stack up under SA law. I do think that had there in fact been an intruder, shot in the circumstances of this case, then the shooter, would never have been charged, and so a complete acquittal of OP is a possibility. If there is a guilty verdict on some lesser type of homicide, that in itself must validate/confirm that OP believed he was shooting at an intruder. A lesser charge should not be an option if the Judge believes that OP was shooting at the door KNOWING Reeva was behind it.
