You don't shoot and kill someone because they punch you in the face.

This was a fist fight the ended up with the two of them rolling around on the grass. Zimmerman got a fat lip and two small cuts. His life was never threatened, nor he sustain any serous wounds. He did not go to the hospital, nor did he go to a doctor directly after the event.
