ITA with all you state here.
I'm gonna get roasted here, but the ME left me worried and a bit disturbed. He was dismissive, arrogant, and quite honestly, left a lot to be desired in his answers.
I think JW was way over her skis on cross though, which left her lacking on her questions, but the jury may have picked up on his less than desirable/detailed testimony
From at least one of the juror's questions, they are examining the notion of "what if the gunshot was first?" The ME wasn't convincing enough to preclude this possibility from their consideration.
However, I can't say it really matters when looking at all the other evidence, of which there is a ton. Even if someone believed her tale, how can the overkill be explained? It can't. But I don't think they will believe her. Her lying was so flagrant -truly incredible. Who would remember, in the heat of a fight, that she "rolled to the left..." Her story is the culmination of 4+ years of jail time, during which she crafted this implausible (impossible?) saga. And the fact that it's fiction is very clear IMO. I think we're just gun shy because of the CA case...
