I think the best evidence - objective Experts, the best of the best, who didn't speak for either side, and simply presented their observations as Experts - made it literally impossible that KR did anything wrong. They even said that. Not possible. They concluded, on a scientific basis, it was "not possible" that she hit him, and "not possible" that the taillight was damaged by collision with JOK, not in light of those injuries and that setting.
The only person who said otherwise was Paul, whose theories and testimony were so unprofessional and convoluted that it was literally laughable to observers. He was clearly no expert. But his job was to spout the prosecution line - he works for them, so very far from an objective evaluator - so what else was he gonna say? He admittedly made up as good a tale as he could to fit the prosecution claims, with no real backing, because they made it his job. He actually said, while under oath, that the evidence didn’t fit the scenario of a vehicular collision so he made it fit because that’s what his buddies said had happened.
But the science speaks. It wasn't his lack of ability, but rather that the science says KR could not have hit JOK and caused such injuries, leading to JOK being found where he was and his death.
The cherry on top was the testimony from the defense Experts on the arm injuries being dog bites. It was clear and obvious, and was actually either directly supported or not contradicted by any medical testimony by the prosecution. It's informative that Lally said he'd easily bring a rebuttal witness re the defense's dog bite testimony, but then did not -- obviously no one who wants to stick to the truth and who is concerned about their integrity could contradict the fact that JOK's arm was injured by a dog attack. It is what it is.
Once we know JOK's injuries (and the taillight damage) aren't scientifically possible from a vehicle accident as proposed, and that his arm was injured in a dog attack, it's obvious KR didn't do it. She didn't kill him. Couldn't have. How it all REALLY played out? Hope we find out and the perps are brought to justice. It had to be something very different than these people claimed - with no vehicle accident and with dog bites, it couldn't have been her - and it feels like the FBI will weigh in at some point. But it wasn't KR.
