He kept following even after the dispatcher said they did not need him to do it. He put himself into the situation. No excuse for Martin to jump him but also no excuse for Zimmerman to keep following after calling 911. He did not witness a crime.
Just as Martin has the freedom to walk, Zimmerman has freedom to follow. Whoever initiated the physical altercation, is the guilty party. We will never know exactly who that was. Our justice system hinges on giving people the benefit of the doubt, therefore Zimmerman is free. The court system worked exactly as it was supposed to
Again, a dispatcher is nobody. Their advice means nothing.
You don’t need to witness a crime to follow someone in public. And you don’t jump someone just for following you.
Legally speaking, “putting himself in the situation” again, means nothing.
