In the United States, we (are supposed to) believe that you are innocent until proven guilty.
Trayvon Martin never had a day in court to face accusations and defend against any actions or activities that may or may not have been deemed "suspicious" and more importantly criminal or threatening. The color of his skin and the clothes he wore are not enough to render judgment about his actions or intentions. Neither is it the duty of a private citizen to make such a judgment and take matters into his own hands in rendering a sentence of death.
George Zimmerman has admitted to shooting this 17-year-old, claiming he felt threatened and calling his action self-defense. I cannot judge him for I don't know all the facts, and I still believe in the idea of innocent until proven guilty.
And so I believe that Mr. Zimmerman should have his day in court. He should face allegations and charges for an action he has admitted to taking and present his defense -- before a judge and jury of his peers. That public opinion has proven necessary to push for that day is a sad commentary, but I don't believe that either the young Mr. Martin nor Mr. Zimmerman should be tried in the court of public opinion (or we are no better than him whom we accuse). Our outcry must be for justice not revenge; truth not vengeance.
Let justice be served and the truth exposed, even if the truth hurts. Lady Justice is blind but that doesn't mean she turns a blind eye...
