Video was pretty decent for me on Chrome, but tomorrow's another day, another adventure with L & C.
I like science, I find it fascinating, and although it's never been a professional calling for me, I've used it in my life without thinking about it.
The witness, Jones, was stellar if you wanted someone to explain DNA. I'd say he's one of, if not the best witness for DNA analysis of the many trials that I've watched.
I think the defense blew it in their cross. The witness was more knowledgeable about the subjects that the defense threw at him than the defense pretended to be, IMO.
He didn't speculate, he gave the findings of his data.
Here's something I ran across ages ago;
"Objectivity in science is an attempt to uncover truths about the natural world by eliminating personal biases, emotions, and false beliefs. It is often linked to observation as part of the scientific method. It is thus intimately related to the aim of testability and reproducibility."
I believe that's exactly what Mr. Jones did in his testimony.
