Maybe I'm wrong, but from what I've read the ONLY thing that matters here is Zimmerman's story of self-defense holding up.
As long as the prosecution can not PROVE that Zimmerman was not at an actual physical risk of severe injury or death then Zimmerman should face NO legal repercussions.
things that
don't matter:
- what zimmerman thought or felt
- what zimmerman said on the 911 call
- whether zimmerman racially profiled martin
- zimmerman's past
- martin's past
- ANY other racially motivated event in the history of the world
- anything else
The ONLY thing that should matter is Zimmerman's story and the self-defense law.
