Excellent closing.
BTW, I'm surprised the defense pulled their expert forensic pathologist. This was to be the person with more autopsies and experience under his belt who was going to smash Simmons "amateur" states (in the defense's eyes).
Maybe Simmons did such a good job the def. team could see the flaws in their own expert's opinion and were afraid he'd end up uumin and aaahing like Knox. He'd possibly end up saying "could have" instead of "was" as to how the bullets struck Jordan in tune with the defense story.
Another thing we may never know.
