Based on similar experiences I've had, I'd guess you can just backtime starting about twelve seconds before the shot. I think the shouts were as heard on the Lauer call, and there were just points where he was doing something other than focusing on the sound, so he doesn't remember it. That's not uncommon in recalling traumatic events.

There's sort of a reverse of the same phenomenon in the walkthrough, where Zimmerman doesn't remember calling for help until Good sticks his head out. As far as his specific recollection he said he didn't time his everyday life, but figured 1 to 2 minutes, then Bernie asked 2 minutes, and he said that was possible.

I believe you are mistaken, go back and watch the video again. George states that he began calling for help as soon as skittles started whacking his head on the concrete.
After John came out and John said he was going to call the police, George said that he already did, what he needs is help.

When John Guy opens his door they are right there — about 35 feet down from the T where the first punch was thrown and that had to take some time — perhaps a minute.

Then from when he sees them until he hears the shot — another minute.

So we are up to two minutes from first blow to gunshot.

From the time GZ hung up the phone until the gunshot was about 3 minutes.

That leaves one minute to look around for a street sign, try to get the flashlight to work, walk the 30 feet back down the sidewalk to the T,.... and take the first blow.

There would have been no time for anything else that the prosecution will allege took place like ... following, chasing, arguing.

How are they going to try to wriggle their way out of this??
