The improbably named "Trayvon" (huh?) Martin was killed while in the act of committing aggravated assault. That's not murder. The author is stupid.
>> There is a deep seated feeling of injustice and lack of closure

>> And, the “Stand Your Ground Law” which provided George Zimmerman
And ... the author progresses from stupidity to outright lying.
Plonk.
Not stupid - a liar. He knows the difference.
