(Cincinnati) --  Hundreds of people in Cincinnati are upset with last week's acquittal of George Zimmerman in Florida.  He was charged with murder in the death of unarmed teenager, Trayvon Martin, in 2012.  On July 13, a jury found Zimmerman not guilty.  A week later, demonstrators gathered outside the Potter Stewart Federal Courthouse in Downtown Cincinnati, and outside other federal buildings across the country, to voice their displeasure with the verdict.

Bishop Bobby Hilton of the local chapter of the National Action Network, which organized the protest, says the justice system is broken across the country, and isn't fair to African-Americans.

Hilton told the crowd without justice, there would be no peace.  Other speakers at the rally decried black-on-black violence, and urged a peaceful resistance to injustice.

Protesters want the Justice Department to open a civil rights investigation into the case.
