The actual words as edpc points out:
Bao: “Nobody knows more about Trayvon Martin’s autopsy than me.”
West: “Except you don’t remember anything about the autopsy”
Bao: “Yes, without my notes.”
[Unless I am mistaken I don’t remember the state ever entering Bao’s autopsy into evidence. And Bao is up on the stand being questioned about this autopsy and he doesn’t even have it in front of him — just notes that were not even taken from the autopsy]
I think he was just 'assisting'. He is the 'assistant' ME. BUT, it was thought that by using a CHINESE man (a trainee) instead of the actual person who did the examination (probably the technicians), the Jury would be impressed by his 'kung fu' and ignore any inconsistencies and chalk it up to 'miscommunication'.
