If they had the evidence, they would have put it on. Mimi said TA said she came in the doggie door. No one else has said this. TA told people she stalked, slashed tires, but no one has testified to that and there is no proof. (IIRC, the jury hasn't heard about the tires.) TA said a lot of bad things about her. But then he also portrayed himself as virgin devout Mormon, so there is a credibility issue there. I realize 99% of posters here believe everything JA says is a lie (yes, I know she has lied a LOT and she absolutely has big time credibility issues), and TA is the greatest guy, but I don't think the jury will see it that way. He snuck around misrepresenting his relationship w/JA apparently due to his friends' disapproval. So what else did he say or allude to them about JA that wasn't true? I think the jury will generally think they're both screwed up and were in an extremely dysfunctional relationship.
At this point based on what i have heard, I can p see her pre-meditating and murdering TA by gunshot. That would be part of a calculated plan and would be physically easy to do. Aim the gun, pull the trigger. But IMO, it would take a huge amount of rage to do the knife violence. I can't imagine going from calm and composed (taking pix) to slashing someone's throat. It would take a rageful adrenaline rush to garner the physical strength to do that, I think. So I still feel something triggered the knife violence and it wasn't part of her plan.
I just wanna hear her (current) version of how she ended up at TAs house and how the killing happened. Maybe by March they'll get to that.
