I was watching some of the trial and found a few things interesting.
1. The judge denied one of the defense teams "expert" witnesses. This is something that in general, I'm against. In this case, it was absolutely the right decision because there was nothing expert about what the defense wanted to do. It is however testimony you often get to see in trials. And usually when you see it, it leaves you thinking the whole thing is sham, so far as passing off someone as an "expert", when its nothing more than sheer speculation.
In this case, the defense wanted to use an expert witness to testify the positions he believed the victim to be in, and the defendant to be in, when she shot him. He was going to do this based entirely off the trajectory of the bullet that missed him and hit the wall. The judge, who admitted several times she isn't a geometry or trigonometry expert, kept asking how that would show with any scientific basis the trajectory of the bullet that did hit him, and where/how he was positioned. Which is a pretty damn good point. The defense tried to say it was the same thing as a medical examiner giving an opinion, which the judge rejected, because it's absurd. She definitely got this one right.
2. This was the most interesting. Usually, the prosecution calls on some police use of force expert, not the defense. Because usually, it's not a cop on trial. Here, we saw the exact opposite. What an interesting dynamic. If you didn't know ahead of time, when the defense was asking questions you would have sworn they were the prosecutor, and vice versa. It perfectly illustrated how blatantly biased these so called witnesses are, and how unfair trials in which prosecutors use them in are.
During the hearing to determine whether this witness would be allowed, he gave his "expert" opinion that her use of force was reasonable, and that she believed her use of force was reasonable, based on his training and experience. You all know the shtick. The stuff prosecutors when it's the other way around LOVE. Of course here, they objected. They accurately pointed out that whether her force was reasonable is the job of the jury. The judge agreed. She is limiting his testimony only to, based on his training and experience, people in a similar situation, or under stress, what physical sensations someone might experience. The judge again made the right decision.
That whole thing completely exposed how corrupt prosecutors are when they use these so called experts to give their personal opinions, which nearly always are that whatever force a cop used was reasonable. They know it's a jury's job to do this, and that it's purely a biased opinion, not an expert one. Yet it's almost always allowed. I'm hopeful this judge is actually an honest and fair one.
With that said, I still don't see a murder conviction. And with the prosecution focusing on that, and not negligent homicide, their chances of a conviction for that also decreases. If they focused on just a negligent homicide or manslaughter or whatever it's called in Texas, they'd have a great chances, just based on her testimony alone. Seeing pictures of the apartment, the red mat, her testimony she heard noise before she entered, the 911 call, her after actions, her focused on the affair she was having, deleting texts off her phone, it's seems rather clear to me her shooting him was a result of her own criminal negligence.
