No big deal, it never had to have a racial element anyway. The fact that he said he was following him because he matched a description of supposed burglars covers it pretty well.
There is however recent news of Zimmerman harassing a co worker with racist remarks as well. He's probably somewhere in the middle on the issue.

But I still think it's more likely that he just over reacted, or reacted in a way he thought was needed but it turned out it wasn't needed at all. He sure didnt' appear to be near death anyway.
