A welcome change in Ferguson, Missouri. Protests were boisterous but peaceful as demonstrators took to the streets for a fifth night over the killing of Michael Brown, an unarmed black teen shot by police. A big change after nights of unrest filled with violence and tear gas. "Say what you gotta say, just do it in peace." The change came as Captain Ron Johnson of the Missouri Highway Patrol took over security after the governor stripped local police of their duty.
