I don't see why OP's probably unfaithfullness to Reeva should be classed as character evidence and inadmissable. Surely it's evidence he lied when presenting the court with a picture of a perfect relationship and his deep and serious love for Reeva? As for his phone being removed from the scene of the crime and tampered with..how that didn't come up I just don't understand.
In fact, I don't really understand the reasoning behind the evidence prosecution chose to present, and chose not too. It's very strange.
It really will be a travesty if OP walks free at sentencing.
I have to say I was deeply disappointed by the way the prosecution was conducted. I kept hoping and trusting that everything would be brought together in a devastating closing argument, but it never happened. I realise that not everything was admissible, but still so much incriminating evidence was downplayed or not presented at all. I was mystified by Nel's "Baker's Dozen" points - there were much better points to be made afaics.
Carl Pistorius' tweets seem incredibly insensitive to me. I think they indirectly reflect badly on Oscar too. But they both seem too insensitive to realise.
Or maybe it's just me being too sensitive to the idea that with OP's horrific gunning down of a young woman still so present, a little restraint and decorum is called for?
I'm sure they just regard this little local difficulty as a "hurdle", to quote the victim. These people disgust me.
