You think they'll show him crime scene photos? I honestly don't know whether they can/would/should do that.
bbm -Just catching up again, but yes I would think that since they are to be testing his responses about that night and what could have led up to, it I would expect some of those too(though maybe not start with them...), along with perhaps childhood photos, photos of different family members(father, mother, brother, sister, uncles, aunts), friends, business associates(coach, financial advisors, lawyers) previous girlfriends(if there is one the balloons in the trees for that one valentine's), previous adversaries(Batchelor and his millionaire friend, RS's previous bf's and gf's, the girl in the door incident, the guy he accused of cheating, etc), photos of him both winning and losing the big races, pics of RS modelling, in Tropika and with him, pics of his second home in Italy, his different homes/properties in SA, his current residence, and the prison he may find himself in should he lose.
They should all evoke some kind of response and depending on how they're presented should definitely provide insight as to his personality beyond what his own words may have told them. ie. have him give a brief summary of what they each mean to him upon viewing and weigh that against what his brain activity(EEG) says and whatever facial/body language is revealed.
I sincerely hope they don't just rely on questionnaires and subjective observation, no matter how good they may be. Anyone can google on how a patient typically reacts with any number of disorders/illnesses but his brain activity won't lie.
