So his opinion on whether or not Dr. D was qualified in her expert opinion is based solely on what the Defence team has told him about her testimony.
Bet JW didn't tell him about the part where Dr. DeMarte said "those scales can't be just read and interpreted that way" and JW replied "well, let's do it anyway".
IMO, as long as he hasn't heard or read her entire testimony and only relies on the (at times mis-)representation the Defense team gives, he has no place testifying about it in the first place.
Gosh, this whole testimony makes me angry.
I've said it before and I'll say it now: The problem I have with this case and others like it is that the state and defense teams are, too often, more interested in being right than doing the right thing.
This combative posture discounts the real reasons for the court's existence. A man was killed, murdered.
Martinez is being a total jerk which may disturb members of the jury. They may tune him out just to protect themselves from the unpleasantness. Can he cross examine someone and have verbal discourse without being a bully?
The hysterical yelling and emotive assaults on the witnesses is so off putting!
Oh please make it stop! Finishing school. Please send him to finishing school for some polish. Because the roughness distracts badly from his good points.
