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

125. My response

At 5' 9" every BMI chart I' looked at puts him 20 lbs overweight.

185-200 lbs at 5'9" classifies as overweight BMI, but not obese. However, BMI is not always an accurate assessment of fitness: "Athletes sometimes get the short end of the stick when it comes to BMI results. Because BMI is based on height and weight, muscle mass isn't taken into account and muscle-bound athletes like football players, body builders and softball players often test at overweight or obese levels."

ETA: You made some pretty huge assumptions in the post I was responding to: "Zimmerman is a lard ass, and NO WAY NO HOW could have outrun a 17 year old football player. (That's logical). If Trayvon took off running, as Z stated, he had ample time to get home WAY before fat boy could have caught up to him."

How do you know that? If you hadn't seen the 2005 mug shot when Z was very overweight and your first image of him was either the police video or Z at his arraignment, I doubt you would have come to that conclusion.

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!

It's based on an expert opinion. I watched a retired police officer (sorry, can't remember the show) make observations about the police surveillance video when Zimmerman arrives at the station. He noted that Zimmerman moved easily and fluidly throughout the video, but most tellingly when he exited the car. Most people use at least one hand, on the door handle or the seat, to give them leverage when they're getting out of a car. When you're handcuffed, you don't have a free hand to use, so usually a police officer will help you out. The retired policeman pointed out that not only did no one help Zimmerman get out, he didn't need anyone's help.

===============

You're right, I don't know if the doors were locked, or if there was a hidden key. But going home, even if home was easy to enter, opens up the possibility that Z is still following and would see where he was staying. In addition, both his dad and the future stepbrother's mother said the two boys were close, and Trayvon was buying Skittles for him. So yeah, I think there's evidence he'd be concerned about leading Zimmerman home where the younger boy was waiting.

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.

I think you're lying when you say you haven't taken a side. Z's injuries weren't consistent with his head being slammed against the concrete, and T's injuries (to his hands) weren't consistent with beating someone. Furthermore, confronting the threat doesn't presume violence--"What are you following me for?!!" is confronting it. You're the one suggesting that means Trayvon struck first, and we don't know that.
