I can't seem to see my comment above, what I see instead is "Suspicious Comment."
I have a day job and I tend to ignore polemic screeds such as the one you linked.
Fortunately, the inflammatory and inaccurate summary created by a highly biased source actually linked to reliable source information, as here: http://www.thedailybeast.com/articles/2012/03/23/did-trayvon-shooter-abuse-911.html
For example, the call regarding a 7-9 year old makes total sense in the context of the raw logs:
"COMP ADVS S43 IS WALKING ALONE & IS NOT SUPERVISED ON BUSY STREET // COMPL CONCERNED FOR WELL BEING."
This by the way makes the article you quoted a flat out lie, "There is no indication in the police report of the reason for Zimmerman’s suspicion of the boy."
I'm not buying the claim that Zimmerman is a racist. I'm clear that he's a killer.
What I'm watching in disgust is everyone else's racist reactions, and I feel comfortable in including the article cited as among those racists.
