It's not a completely illogical conclusion. The problem is the state hasn't explained it just might not ever get around to it. So it's all conjecture. The tiles don't look consistent with having been with a bat to my untrained eye. I'm not morphing what I see, that's what I see. And why doesn't the state have a theory on this stuff? Didn't the police question Oscar about the damage? If not why? Surely, at some point, Oscar must have explained the extra damage, if not, then it's just more evidence of shoddy investigative work. So here are the possibilities:
Oscar has explained it, his explanations were, at the least, reasonable so Nel decided to leave it at the power of suggestion and only put the pictures up. He won't ask Oscar about it.
OR
Oscar has not explained it and Nel doesn't want to dig further, again, preferring the power of suggestion
OR
Oscar has explained it and Nel, dissatisfied with his answers, is waiting to bring it up and nail him on cross examination.
OR
Oscar has explained it and Roux is waiting for the opportunity for direct examination to allow him the opportunity to explain the damage.
The trial isn't over yet and I'm not really comfortable with filling in the holes myself. I mean, I could, and the explanation that Oscar was on a rampage is not beyond the realm of possibility, it's just conjecture right now.
