Looking at the undisputed facts in the Zimmerman case and applying Zimmerman's original story

[Spoonman]

119. Assumptions Again.......

Point by point:

He looked like he was pretty fit in the police video taken the night of the shooting.

"Looked" - I've seen woman from 50 ft away that looked stunning, but up close looked like boot leather.
Z's weight was never listed, only his height. His weight has been estimated at 70lbs
At 5' 9" every BMI chart I' looked at puts him 20 lbs overweight.

He also exits the police vehicle in handcuffs unassisted--something that is difficult to do unless you're in pretty good shape.

Is this an expert opinion? How would you know?
Was the back seat of the police car more conducive to the ability to do this more than others?
HUGE assumption!

1.

continue home, ring the doorbell (he had no keys) and have it answered by his 14 yo future stepbrother, thereby putting the younger boy as well as himself at risk;

First off, you are assuming what he was *thinking*.
Was the front door locked?
Was the back door locked?
Was there a hidden key somewhere on the porch?
Does he give a shit about his *future* stepbrother?
Tons of assumptions here.
I would highly doubt he would have the gone through the in depth thought process you outline if indeed he was "terrified".

The FACT is that he didn't go home, and had more than enough time to get there regardless of what he was thinking.
We know this because he was shot outside his house, get it?

2.

hide out until he thinks the threat is gone (this is what I think happened)

OK, so he hides out and Z finds him, what next?
a. Z begins to question him and Trayvon becomes the aggressor - Z has broken no law, and Trayvon is subsequently justifiably killed
b. Trayvon gets pissed off and steps out of hiding to confront Z, becomes the aggressor and is subsequently justifiably killed
c. Z shoots him in cold blood, smashes his face against something to break his nose, rolls around in the grass and slams his head into the concrete causing the abrasions.


3.

confront the threat

a. By confronting the "threat" I will assume you meant to say Trayvon stuck Z, and thereby becomes the aggressor and is subsequently justifiably killed
b. Z shoots him in cold blood, smashes his face against something to break his nose, rolls around in the grass and slams his head into the concrete causing the abrasions.
