My sister, who is my own "mock juror" says she immediately took a liking to Dr Vass and understood his testimony when JA was up, and she was totally engrossed. She said Dr Vass is delightful, and she just wanted to hug him. She said it's clear he loves his work and is passionate about it.
In her opinion, Baez personally attacking Dr Vass is upsetting the jurors and this will totally backfire on the defense because attacking the good Dr is all Baez is doing.
She said if she were on the jury, she'd loathe Baez for this.
My own opinion is Baez's inexperience is glaringly obvious during this cross.
