A couple hundred pages ago I was called out for saying Zimmerman "decided to take a gun and pursue him" because it was taken to mean that Zimmerman armed himself with the express purpose to pursue Martin.
I know these discussions evolve at times to pissing contests, but you seem fairly willing to discuss facts and evidence.
The thing is, that the law says two very different things about the snenario where an armed Zimmerman is invloved in a confrontation and the scenario where Zimmerman is involved in a confrontation and then arms himself. I know that's not exactly your claim in that instance, but the disctinction is not meaningless all the same.
It's the same with the current iteration. Zimmerman confronted Martin is legally disctinct from Zimmerman and Martin were involved in a confrontation.
