We Want an Arrest, Shot in the Chest': Protesters March in Florida for Trayvon Martin

Thousands of people marched in Sanford, Fla. Saturday to honor Florida teen Trayvon Martin and demand the arrest of George Zimmerman, the neighborhood watch volunteer who shot and killed him.

"We want an arrest. Shot in the chest," protesters chanted as they made their way to the headquarters of the Sanford Police Department, which has overseen the case. Others marchers carried signs that said, "Justice for Trayvon."

Zimmerman, 28, said he shot Martin, 17, in self-defense last month after Martin attacked him. He has not faced any charges thus far, claiming protection under the state's "stand your ground" law.

"We live in the middle of an American paradox," Rev. Al Sharpton, attending the rally, told the crowd. "We can put a black man in the White House but we cannot walk a black child through a gated neighborhood. We are not selling out, bowing out or backing down until there is justice for Trayvon."

Sharpton has vowed to call for an escalation of civil disobedience of Zimmerman is not arrested. At a press conference before the march, Sharpton and NAACP President Benjamin Jealous denied reports that included an economic boycott of Sanford, calling it a "media fabrication," according to MSNBC.

"Put to rest the rumor that there is any discussion of a boycott of the community," Jealous said.

Rev. Jesse Jackson, who also spoke at the rally, similarly vowed more civil disobedience.

"This is not about a hoodie, it's about racial profiling," Jackson said. "We will use our marching feet, civil disobedience and every weapon in in our non-violent arsenal until justice is served."
