Civil rights leaders Jesse Jackson and Al Sharpton will be in Sanford, Florida, for a town hall meeting today about the death of Trayvon Martin. A 17-year-old African American, Martin was shot dead while walking in a gated community last month. He was unarmed. Martin’s shooter, George Zimmerman, has not been arrested or charged. On Sunday, Jackson characterized Martin’s death as a transformative event reminiscent of the killings of Emmett Till in 1955 and Mississippi civil rights activist Medgar Evers in 1963.

Rev. Jesse Jackson: “How do we take the light of the martyr—Trayvon is a martyr. He’s not coming back. He’s a martyr, murdered and martyred. And now we must illuminate the darkness with the light that comes from the martyr.”
