NEW YORK, CMC - Caribbean American congresswoman Yvette D. Clarke has joined members of New York City Congressional Delegation in calling on the United States Department of Justice to conduct a “thorough” investigation and possible prosecution of a white neighbourhood watch volunteer who killed an unarmed black youth in Florida. On Saturday, an all-white female jury in Florida found George Zimmerman, 29, not guilty in the February 26, 2012, shooting death of Jayvon Martin, 17, in a quiet neighbourhood in Sanford, Florida. After three weeks of testimony, the jury rejected the prosecution’s claim that Zimmerman had deliberately pursued the teenager.
