No, why should they? If some asshole was following YOU down the street when you are walking home and you tried to employ some evasive tactics and they came up on YOUR ASS, what would you do?
Well, first off, you don't know how it went down.
Secondly, even if your suspicions are true, all that means is that YOU think the wise course was to engage in combat with the armed neighborhood-watch guy.
It might make a little bit more sense to continue to walk away or evade the guy rather than to become an aggressor. At he very least, we now know how
that worked out. Not well. Very sad. Tragic.
So, that COULD be a clue that YOUR way isn't the right way.
Was the kid walking and did the asshole follow him?
You don't know. You may THINK you know, but you don't. And that's kinda the point. The kid MAY very well have been just walking. And the person you cavalierly label "the asshole" MAY have followed him. And that might not have been improper.
Did the kid notice that some asshole in a truck was following and state such to his friend on the phone?
The kid MAY very well have noticed the neighborhood watch guy following. YOU still don't know, but let's go ahead and assume it's so.
Did the kid try to evade the asshole who was following him?
YOU don't know. He may have tried to evade the neighborhood watch guy who may have been "following" him. If so, that might have been a good idea.
Did the asshole call the police and state that he was following the kid?
Did the negihborhood watch guy continue to monitor the kid? Apparently. Yes. And as I understand it, he did tell the 9-1-1 operator that he was following. Yes.
Did the dispatcher tell the asshole that he doesn't need to engage the kid?
No. What the dispatcher told the neighborhood watch guy was that he didn't need to follow the kid any further. The "engage" shit is all yours.
Did the asshole NOT HEED THAT ADVICE?
Did the neighborhood watch guy continue to follow and observe the kid despite having been told that he didn't need to do so? Evidently, yes.
Did the ASSHOLE get out of his truck and confront the kid who was simply walking down the street?
Did the neighborhood watch guy get out of his truck and "confront" the kid? Possibly. YOU don't know that, however. And WAS the kid merely walking down the street at that point? YOU don't know.
Maybe the kid felt he was cornered
Maybe. And maybe he was wrong. YOU don't know since YOU weren't there.
and did the best thing he thought he could do to defend himself.
Maybe. YOU don't know. But if he DID, maybe it wasn't such a hot idea.
I don't care if Zimmerman was Black, Asian, White, Mixed race, etc., he could have kept observing the kid from afar, instead he chose to confront him.
YOU don't know that. It is possible that the kid chose to actively confront the neighborhood watch guy.
Because that asshole chose to do that, there is an unarmed kid who is DEAD.
YOU don't know that. YOU weren't there. YOU are engaging in rank speculation.
ETA: I don't even think that a police officer would have the PC to stop this kid even for a "Terry Stop", so what gives this civilian a "right" to do so?
YOU don't know that. But YOU also don't know that the neighborhood watch guy "stopped" the kid or even tried to. Monitoring may have been all he was doing, and possibly (YOU sure don't know, and neither do I, but unlike you, I don't claim to know) -- possibly the kid chose that moment to run up on the neighborhood watch guy.
Bottom line: YOU don't know even half of what you are assuming. And it remains quite possible that the neighborhood watch guy didn't actually do anything wrong.
On the other hand, it is possible that the neighborhood watch guy DID do something wrong. Just like YOU can't actually tell us, neither can I. But -- and here's a kicker YOU cannot get around -- the eyewitness who evidently spoke to the cops provided information consistent with much of what Zimmerman had described. And that might very well mean that the cops also did nothing wrong by electing not to make an arrest.
