George Zimmerman was in a locked car with a gun. He was safe. When he started to follow Trayvon, he was told that he did not need to do that. He continued to follow him. The gated complex was 20 percent black, so seeing a black teen should not have been suspect.
I grew up in Alabama and still visit my many relatives living there. Race relations have changed very little during the 50-plus years I have lived in California. In all honesty, I don't think Zimmerman would have followed a white teen.
