Anyway, who called for help may or may not be material. We don’t know the story. What we know is that Zimmerman went out looking for Travyon, armed, wanting a confrontation, that he disobeyed police instructions to not do so. If a guy with a gun came up on me and threatened me with it, I’d like to think I’d keep my cool and try to talk him down, but I might panic and hit him or try to grapple for the gun.

We don’t know, and may never know, what went down. What is obvious is that Zimmerman initiated the confrontation after being explicitly told not to, so the results of it are obviously in a large portion his fault.
