Blair L.M. Kelley on Trayvon Martin, Emmett Till, and Mourning

Over at The Grio, Blair L.M. Kelley writes of the role mourning has played in the aftermath of Trayvon Martin's death and the acquittal of George Zimmerman. Kelley also examines the similarities between Martin and  Emmett Till. In both cases, there was a public outcry generated over the crimes, the killers were found not guilty, and the unjust verdicts outraged many Americans. Kelley places Martin's death within the larger history of racism, white supremacy, and violence against black people in the United States:

But the trial only came after Mamie Till publicized her son’s murder by holding an open casket public viewing of her son’s mutilated and distended body. News of Till’s murder reached a national and international audience when pictures of Till’s corpse were published in Jet magazine. Many of the thousands who attended the public viewing and millions who read of his killing demanded that a trial take place.
So it would be Mamie Till, despite her personal grief over the death of her son, who would take the story of the case further, demanding that federal authorities bring charges in the case after Bryant and Milam confessed to the killing in the pages of Look magazine. It would be a national mourning that made the Till case a touchstone for a generation that had been encouraged by progress in the push for civil rights, and yet devastated by a blatant miscarriage of justice in a southern court.
This time we are mourning for a boy from Miami, visiting his father in Sanford, Florida, unaware of the racial terrain in a neighborhood with some crime and an overzealous neighborhood watchman, driven by assumptions. While I am almost sure Trayvon Martin’s parents, Tracy Martin and Sabrina Fulton, talked with him about being cautious and respectful if approached by the police, I’m sure none of their advice prepared him for being followed by George Zimmerman. 
We are mourning because Martin’s death at the end of Zimmerman’s gun was initially dismissed by the police as a “Stand Your Ground” case of self-defense, Florida’s version of an ALEC-sponsored law that, unlike most self-defense laws does not require that self-defense is the last resort of someone who cannot escape the altercation. We are mourning that any fistfight might turn into justifiable homicide. 
We are proud that Martin’s parents had the courage to publicize their son’s death in order to push for a trial, but we are mourning because unequal justice still seems to be the norm. We are disheartened because we know a Florida woman, Marissa Alexander, is not allowed to stand her ground against an ex-husband with a documented history of abuse, but Zimmerman was found by the court to be justified in believing he needed to kill an unarmed stranger. 
And sadly, despite all the changes that have occurred over the past five decades, many of us are mourning, worried about what we should tell to our children that might just keep them safe, as if some set of behaviors could prevent them from being perceived as a threat. We mourn for all our boys.
