That is speculation on your part. It is either self defense or something else. If it is self defense then none of the something else matters.
I disagree.
I think the evidence clearly demonstrates that George Zimmerman strapped on a gun and walked out his door for the express purpose of looking for trouble.
I don't think he walked out the door looking to kill anyone, I don't even think he walked out the door looking to shoot anyone.
But I think it's clear that he has some strange hero predilection and when the police department he applied to declined his application (I would have to assume for cause) and the security guard job he had fired him for being overly aggressive he set his sites on a completley unregulated and unsupervised channel through which to scratch his wanna-be law enforcement/authority figure itch - self-appointed community watch captain.
So ol' George was out there with his gun on his hip stalking the neighborhood like he was Wyatt Berry Stapp Earp looking for a cattle rustler (or teenaged kid, any port in a storm) to "bring to justice.
When he saw one he aggressively pursued the kid, in the rain, in the dark of night, and I would have to believe he scared the daylights out of the poor kid. I mean, how does this kid know that Zimmerman is the wanna-be block watch? He didn't identify himself in any way. He just crept around in the dark. I have to put myself in Martin's place and if I were a 17-year-old kid today and some middle aged guy was stalking me through the neighborhood in the dark of night my first inclination certainly wouldn't be that "Hmmm, must be the neighborhood watch". I'd think he was a murderer, a rapist, a kidnapper, whatever, something along those lines. Because let's face it, well adjusted grown men don't drive around at night looking for kids to stalk.
So Zimmerman pursued Martin, but Martin was able to get away.
It would seem as though Martin went so far as to hide in the bushes to escape from this nutcase, or at least that's what would had to have happened if Martin was later to have attacked Zimmerman from ambush.
But the only way Martin would have been in a position to have ambushed Zimmerman would be if Zimmerman had reestablished (or at least maintained, but I think there's evidence that he broke it off for a while) his pursuit.
So, after having evaded what he must have though was some kind of criminal stalker (because, again, Zimmerman hadn't identified himself in any way to the contrary), and after having thought he actually lost the guy, here comes Zimmerman again walking up the sidewalk or across the grass, creeping around, peering into dark corners, obviously still looking for Martin.
At this point Martin says to himself, "You know what? Enough off this running away. I'm going to
stand my ground."
And he does.
But Zimmerman has a gun, and as we all know you don't bring a pair of fists to a gun fight.
So despite doing his best (as best as any 17-year-old kid could do) to protect and defend himself from an adult who was acting in a manner completely inconsistent with every adult I know (and probably every adult Martin knew) Martin wound up getting shot and killed.
Not "murdered" mind you. I don't think, and never have thought, that Zimmerman murdered Martin (in any degree).
But Zimmerman's
culpable negligence put him in a position where a young, dumb, and full of cum 17-year-old kid thought that his only way out was to fight for his life.
If Zimmerman doesn't strap on the gun, leave the house for the express purpose of playing Junior Assistant Police Officer, doesn't (completely inexplicably) stalk a young kid through the neighborhood, in the rain, at night, doesn't fail identify himself in any way, then no shooting occurs.
Zimmerman recklessly acting without reasonable caution put Martin in a position where he was at risk of injury or death.
And that, ladies and gentlemen of the jury, is culpable negligence. That is manslaughter.
I rest my case.
