I think you will find that you aren't the only one.
Those who read a little here, a little there get jumped sometimes for not knowing the correct answer to something.
That is really unfortunate,because those who study and study, and research, and dig on this case, don't always get the correct answer either.
This case is so full of lies/half-truths, things the police should have investigated and made clear, but ignored, and trying to follow the prosec. or defense lawyers, and the testimony, and come up with a conclusion is almost impossible. If you listen to the PROSEC question a witness, you have 1 view, if you listen to DEFENSE, you have totally different view, if you listen to both, and have a way to compare each statement made to statements that refer to it, well, you either have a photographic type memory, with the analytical speed and storage capabilities of a CRAY computer, or you get this distorted, they said this, he said that and you missed some, and WHO KNOWS WHAT THE HELL THE TRUTH IS?
That is what a court trial is all about.
