This is at least in part why I ponder whether manslaughter wouldn't have been a better charge, of course. The core of the incident seems to stem from Zimmerman trying to be too much of a vigilante, rather than following NW protocol -- but poor judgment doesn't equate to intent to kill.
I consider it highly unlikely that Zimmerman, when he got out of the car, had anything more on his mind than playing cop and detaining Martin until the police arrived. Circumstances like this, of course, are why the real cops do NOT want civilians doing this sort of thing, and why the NW guidelines all say some variant of "observe, but do not engage".
I think there is an escalating intent. When George gets out of his truck, it isn't like a mad dash as seen on TV with the cop leaping out of the cruser before it comes to a complete stop and running several yards to tackle the perp. You George seems to take his time getting out, even pauses to lock the doors (twice).
I don't know what George's plan was. If George intended to watch for Trayvon exiting the neighborhood, he could have just driven straight east on RVC to the next corner and gotten a clear view down to the south. Or follow Twin trees and watch the exit from the west.
The only thing George could accomplish going into that alley way on foot would be to find Trayvon hiding in the dark. If that's his plan, he better remember to bring a flashlight. The alternative hypothesis for George after a quick search and not discovering any ******** hiding along the way would be "he ran".
We may not know for certain which way George went while talking to the dispatcher on the phone. Whether he went on to RVC or south "in the same direction as" Trayvon, but George is probably walking slowly back to his truck. Even if he went east, does he then go south when he gets back to tee? He came in here looking for this kid and he's already told the dispatcher that he's not going straight back to his truck so they'll have to call him to find where he is when they get into the area. He doesn't need a flashlight to see the path down the center of this open area with street lights illuminating the area from both ends.
The initial encounter was probably somewhere near the tee.that's what George says, that's what witnesses say and there has been no evidence to the contrary. Noe that George has found Trayvon, his intent should shift to stalling for time till this cops arrive. A friendly neighbor approach would be great here. Something like "Hi, I'm George Zimmerman, I'm the neighborhood watch commander for this community. I don't recall seeing you before, are you new to the area?" The tactic here is delay. The cops are already on the way and the longer you talk, the closer they get. Probably the worst approach would be to be demanding like "What are you doing here!" as if you didn't believe they belonged and you intended to do something about it. Of course, what would be even worse would be to make some sudden move as if reaching for a weapon.
What we here from DeeDee is Trayvon saying "I'm not going to run, I'm going to walk fast (or something similar to that). If Trayvom had popped George in the nose, he's not not going to simply walk away. He would either insure that George would not be getting up or he would be running as fast as he possibly could. Remember, the witnesses say this altercation started near the tee and moved south. The loud words continue as trayvon walks briskely away. Does George get back on the phone and call 911 to tell them "the ******* is here now and he's getting away" only to have to explain thay he cannot exactly say where "here" is because he is in a cut through and doesn't know the address? Or does George escalate his intent to physically stopping the ******* from getting away?
About 50 feet south of the tee we find the first real evidence of a physical nature to the altercation. Here we find Trayvon's cell phone that was usually clipped to his hoodie pocket, George's tactical flashlight and the empty plastic 7-11 bag (I'd like to see someone kick an empty bag upwind). My speculation is that Trayvon was walking away, George approached and grabbed Trayvon from behind, Trayvon spun to break George's grip and popped George in the face using whatever he happened to have handy.
As I said earlier, when you hit somebody, you don't stand around waiting for them to get up. That only happens in the movies. You have to either insure that your adversary isn't getting back up to retaliate or you use the opportunity to run away. If help is near by, sitting on your opponent and pinning their arms can be effective. Trayvon is surrounded by neighbors that are all awake. This would work almost anywhere except perhaps a gated community full of scardy-cats that run upstairs and hide when someone calls for help.
Does Trayvon at this point have the right to use deadly force to eliminate the threat of George retaliating? This is an interesting question for debate but there is no evidence that Trayvon continued to fight. George's injuries are consistent with the initial assault to his face and the fall backwards onto the concrete.
Trayvon cannot hold George down forever so for this path of action to succeed, he needs to call for immediate assistance.
George is going to be dazed. He's taken trama to his face and the back of his head. Each time his heart pumps he's going to feel the pounding pain at both sites. In this state he may actually believe he is being beaten to a pulp. If George can substantiate this he may be able to escape the intentional murder charge. How long do we estimate that George has been struggling on the ground under Trayvon? He's managed to rotate and slide off the pavement and onto the grass. But in all this time, he hasn't managed to escape Trayvon's grasp or be killed by those phantom punches. Is George screaming for help? It's quit possible that he did if the broken nose and the accumulation of blood interfering with his ability to breath didn't stop him. We'd also herd that George has memory problems so while he may believe he was the one calling for help, we cannot rely on that as a fact.
The big question comes down to: what is George's motivation when he draws his gun and shoots.
Clearly, if George believes he is being pummeled to a pulp, his motivation is to save his own life. But how long can that belief be held in lue of any actuall pummeling? If instead, the motivation is retaliation for being slugged, George is going to face serious consequences. We can argue back and forth about this but I believe this is a question that a Jury is going to decide.
