the young guy Martin, was walking in the neighborhood. not messing with Zimmerman in any way, probably didn't even know Zimmerman, and Zimmerman sticks his nose in Martin's business. and by doing so in the end, caused the young mans death.
Hahaha how do you know this? Might be a little early to make your mind up. All I'm saying is wait until the trial and hear both sides and then decide because right now it's just one sided info tainted to ones agenda.
