Zimmerman approached the kid in a menacing manner did he not?
Obviously you believe so, but in court, the testimony was that Zimmerman had lost sight of the kid and then the kid approached him.
As i said in a previous post if A guy I didn't know was following me in a car for blocks as I legally walked down the street I would start to feel apprehensive. Wouldn't you?
I believe that the fact that Zimmerman didn't notice Martin until Martin was in the apartment complex, so your characterization of "blacks" seems hyperbolic.
If said person in car pulled up got out of his car and purposefully approached me I would feel threatened. Wouldn't you?
When it's happened in the past to me, I asked "Can I help you?" not struck the person in the face. That might be why I'm still here.
If I told that person to stop coming at me and pulled my weapon I would have been justified wouldn't I?
You might, but according to what was said at trial, Zimmerman didn't access his weapon until he was on the ground being struck.
From what I can tell the kid was doing nothing but walking on the street. Zimmerman approached him with no cause.
Again, apparently the kid approached Zimmerman. You need to educate yourself before you post so you don't waste our time establishing the facts.
