That's what he was trying to claim. He was trying to distance himself from it as best he could but he signed off on it. He is accountable for it. He was the medical examiner for that autopsy and he is trying to blame the technicians who he manages and who wrote down what he told them.
Well he can’t seem to remember what he did 24 hours earlier.
He was a joke for the prosecution. But then again, so was their whole case against Zimmerman.
