Objectively speaking, there were points Baez should have pressed Dr Vass on, but he didn't, which hurt Baez badly, which hurts his client far more. If he really cared about a vigorous defense, he would have passed Dr Vass to Sims. At least she has practical experience, IMO. I have the utmost respect for Dr Vass and his work, but a better lawyer could have done damage control and given Dr Vass' testimony a problem, so to speak.
I'm glad Baez's cross was a fail; he made very little headway and no real dents in JA's direct exam, but I can't help but think Baez's failure is mostly due to his inexperience.
I wonder what the jury must be thinking after Baez's cross.
