Florida, among select other U.S. States, has a "Stand Your Ground" law, which allows one to use force, even deadly, to protect one's self from imminent danger. This is the defense of George Zimmerman, who murdered 17-year-old Trayvon Martin on a street in his dad's middle class, gated Sanford community.
However, 911 tapes do not tell that story, neither do witness accounts. The tapes reveal a scared teenager, who is a minor under Florida law, being stalked, confronted, pushed to the ground and fatally shot, by an unhinged, raging racist, who referred to him as a "fu*king coon" in the audio recording. The law does not cover people chasing, confronting and then killing strangers or people they know on the street. That's called murder or an illegal execution.
At the 2:23 mark George Zimmerman says "fu*king coons"
The other racial undertone present in the case implies a young black man did not belong in a middle class gated community, as blacks are clearly too poor and violent in Zimmerman's estimation, to live in such nice places. After all, Zimmerman barked at unarmed, defenseless Martin, "What are you doing here?" The implication was Martin belonged in the ghetto and was somehow trespassing in the middle class neighborhood his dad lives and pays taxes. The stereotype of he is not a "rapper or athlete" so he couldn't possibly afford to be there is present in all its ugliness.
