The Detroit City Council on Tuesday unanimously passed a resolution calling for a federal investigation to see whether civil rights charges are warranted against George Zimmerman, who was acquitted July 13 of second-degree murder and manslaughter charges in the killing of Florida teen Trayvon Martin.

The resolution, sponsored by Councilwoman JoAnn Watson, sparked a discussion over the need for city leaders and others to focus more on violence in Detroit.

“We need to have that same level of outrage with respect to the black-on-black crime that takes place in our community,” Councilman Kenneth Cockrel Jr. said.
