BZZZT! Once again you continue to claim that Zimmerman confronted the deceased. Please provide ANY evidence of such, other than your own conjecture.
The act of observation set up the confrontation that resulted in the shooting. As Sherlock Holmes would say "Its elementary"
Well, first of all, duh, we know why Zimmerman was observing the deceased, he was on neighborhood watch. One can fairly debate whether or not Zimmerman's attention on Martin was justified, but there is nothing to indicate that Zimmerman did anything more than observe or follow.
YOU are the one making that assumption that Zimmerman caused the direct altercation - with absolutely no evidence to back that up.
But you have consistently pulled stuff out of your arse on this thread, and refused to provide a single link to back up any of your assertions that other posters have challenged.
Sherlock Holmes would be doing a double facepalm at your making up your own facts here.
