I apologize that I miss understood the "white-trash" comment, but the rest of your post is non-sense. How do you know I am viewing this emotionally, or with race issues in mind.
I have been through something like this; and what the cops did was pretty much standard if all the evidence is there.
Your logic is faulty, if someone lives or visits a gated community, then of course there is going to be some sort of neighborhood watch or security; Zimmerman was captain of the neighborhood watch and did what I hope others would do, especially since there were a string of unsolved break ins.
Get off the justice train, if there was a 911 from the kid, it would be in the report.
He is not the innocent little boy you are being spoon fed that he was. He was a troubled, weed dealing (assuming from facebook references), thug wanna be.. and guess what, if you act, look, and try to be a thug, then people are going to treat you and watch you like one.
And yes, that will lead to questions when you are not recognized in a "GATED" "NEIGHBORHOOD WATCH" patrolled neighbor hood.
