“There has been no evidence presented which supports the contention that the 17 year was doing or had done or was going to do anything illegal. Are you suggesting that you are fine with these facts?”
Actually, a witness states he told police he saw Martin on top of Zimmerman, beating him while Zimmerman screamed for help. So. There’s that.
A witness who is unable to testify to who started the confrontation. Whether the 17 year old was on top of Zimmerman is meaningless without knowning what started this incident.
