What We Still Don’t Know About Emmett Till’s Murder - The Atlantic:

Emmett till was killed early on the morning of August 28, 1955, one month and three days after his 14th birthday. His mother’s decision to show his body in an open casket, to allow Jet magazine to publish photos—“Let the world see what I’ve seen,” she said—became a call to action. Three months after his murder, Rosa Parks kept her seat on a Montgomery, Alabama, bus, and she later told Mamie Till that she’d been thinking of Emmett when she refused to move. Almost 60 years later, after Trayvon Martin was killed, Oprah Winfrey channeled the thoughts of many Americans in evoking the memory and the warning of Emmett Till.
