All bullchit and once again you're weaving your scenarios out of George's various stories.<quoted text>
That's a lot of if's, and's and but's. Looking at the map, Zimmerman used the walkway between the houses in order to get an address on the east side of the street where he and Marin parted company. THEN he was going back to his truck (due west) when he and Martin met.
According to neighbors that heard what was going on (but didn't pay too much attention) there were two people arguing with each other. That would explain why Zimmerman walked a few paces north off the sidewalk that went between those two houses. Nothing illegal about that.
Now let's look at the pathway of Martin. They broke off at the north-west corner of the north house, and that's when Zimmerman said he lost Martin. Zimmerman continued his discussion with 911 for about another minute or so. He might have still been walking--he might have stopped. Who knows?
What we do know however is that Martin stayed right there between the houses. He didn't move during that entire time. Now had the shooting took place much closer to where Martin was staying, I would say yes, Zimmerman tracked Martin down. But because Martin stayed there, it tells me that he had plans. He didn't want to go home.
When George said he's running he was still in his truck. George assumed the stranger was running towards the rear gate, he no longer needed an address did he? And the map clearly shows that George was already within 40 feet of an address.
BTW two neighbors paid attention and dialed 911 before witness 6 looked out his back door saw the two on the ground and then had to run upstairs to finally call 911.
