Yes but GZ wasn't just walking down a sidewalk. If you include the statement that was given right after the incident from TMs girlfriend, he was aware that he was being followed and was going to ditch him. At that time the guy follows him into a area so dark that he couldn't be seen. Would you think it must just be some random dude innocently walking down the sidewalk that just seemed to be following you??????? Or would you think you needed to run or stand your ground??
How is it in your mind that TMs GFs statement isn't believable. If I remember correctly her statement came into play very early on. She states he yelled " why are you following me" and then the phone went dead. I believe that her testimony is highly relevant and once again doesn't jive with GZs story.
FWIW you stated earlier that you didn't believe it to murder. I would agree. Personally I believe the charges should be in the area of manslaughter. He didn't set out to kill anyone that night.
