opinion, supposition and conjecture ?
You talk about  GZ initiating a chain of events that need not have  happened. One could easily say TM started that chain of events...
by coming to 'check GZ out' or by running away......
Stop and think, einstein!  GZ was originally  tailing Martin IN HIS CAR! READ THE DAMNED TRANSCRIPT!  As it came out  in the trial, this is why Martin called his girlfriend to tell her that  some "creepy cracka" was following him!
Of course GZ the "cracka" was tailing him...he called the cops and admitted that in the 911 call, so wtf is you point?...the kid could have simply went on his merry way gone home and gone to bed....
GZ not being a cop ?....Not an official member of the watch ?...irrelevant
Only to willfully ignorant, knee jerk bigots like  yourself.  Had GZ NOT decided to play cop, NONE of this would had  happened.  Remember, "we don't need you to do that".
Playing cop ?...opinion, supposition and conjecture, totally manufactured bs from you...
If he was so scared of Martin ?....obviously he wasn't scared at that  point (before being attacked) or he wouldn't have tried to follow him
See above response.
GZ called the police...
 if he thought Martin was armed in some way? .....opinion, conjecture
No stupid, FACT!  READ THE DAMNED TRANSCRIPT....GZ SPECULATED THAT MARTIN MAY HAVE BEEN ARMED!
GZ never said Martin was armed...he did say he had something in his hands so you conclusion is just more conjecture
GZ acted as if his gun gave him the right to play cops & robbers ....more opinion and conjecture
Again, your stupidity shows.....GZ originally  speculated that Martin may have been armed.  So why, after he talks to  the cops and Martin runs away, does he pursue?  What was he thinking?
No stupid, NOT FACT! LISTEN TO THE DAMNED 911 CALL !
and here some more opinion, TM could have disappeared easily in that  neighborhood...he could have gone to the apartment he was staying in and  called the cops, etc.
TM called his girlfriend to tell her he was being  tailed by some "creepy cracka".  GZ PURSUED HIM AFTER BEING SPOTTED IN  HIS CAR.  Had GZ NOT pursued TM, he would have "disappeared".  Your  supposition and conjecture are no substitute for the FACTS.
Had Martin gone to his residence, a few houses away, this would not have happened...fact is, he didn't, he came back to confront GZ and the was beating him as the evidence shows.
So from another perspective, you're guilty of the same things you accuse others of .....
Only if one doesn't read the full transcript and blathers supposition and conjecture as a substitute for FACTS as you do.
You just can't or wont' recognize your own supposition and conjecture in your conclusions....
An unfortunate event but the jury heard the testimony, saw the evidence and rendered a verdict....time to let it go....
Martin’s shooting occurred  only 35 yards from where Zimmerman’s truck was parked, and only 70 yards  from Brandy Green’s townhouse . It would only take Trayvon around 30  seconds to jog that distance, less if he actually ran.... 
 Had Martin jogged straight to  Brandy Green’s when George Zimmerman first reported him running at  7:11:42, he would have been there by 7:12:12. Considerably before  Zimmerman (finished)  giving police directions to the complex....
7:13:41pm: Zimmerman’s phone call with dispatch ends..
Proven by 911 time-line and Martin's cell phone call time....
