So, here's my overall take on the last couple of days of cross examination:
* Oscar is a bad witness. This could be due to a variety of factors, take your pick: He's lying and his whole story is falling apart; He's nervous and not thinking clearly; He's not very articulate; He's confused, etc
* Oscar does shift blame when it would suit him better to accept responsibility for some things and be done with it. I do think he feels a bit victimized about all of this - but that might be understandable if he's telling the truth and it really was a mistake and he didn't mean to kill Reeva. Nevertheless, he should be polished enough at this point to keep that mentality in check.
* I'm not sure what to think about the sunroof incident because he is very firm about that and his voice sounds confident and true - and I also don't think DF and ST are very reliable witnesses. Whichever way the judge goes on this, I wouldn't have a problem
* The Tasha's incident happened and there's no getting around that. Irrespective of Darren's own culpability, Oscar was negligent in the way that he handled the firearm and should receive a penalty for this transgression.
* Nel has effectively raised some questions about OP's ability and willingness to tell the complete and honest truth - or maybe it's better said that Nel has raised some questions about OP's ability to perceive events with accuracy and without defensiveness. If I were the judge at this point, I'd be wondering if there were things that OP left out or spun in his version ..enough that I would consider the whole ball of wax with skepticism, but I wouldn't be convinced that OP's overall account is false, especially since the physical evidence and phone call data and such do tend to corroborate his version.
* If the trial stopped right now, and if I were the judge, I would find him guilty of culpable homicide in the shooting, and I'd find him guilty of the negligent handling of firearm at Tasha's. Probably wouldn't find him guilty of the sunroof shooting only because the two prosecution witnesses both lack credibility and have secondary agendas.
* Based on those verdicts, I would sentence him to 8 years in jail (don't ask me why - it just seems an appropriate number) with a possibility for parole after 4 years.
* It's too bad the police screwed things up and went about the investigation in such a sloppy manner because it's now impossible to know if Nel really made a point about the fans and the various objects in the crime scene because those photos are simply not reliable.
