Protesters marched in Ferguson, Missouri, on Saturday, three weeks after the police killing of unarmed African-American teenager Michael Brown. The officer who killed Brown, Darren Wilson, remains on paid leave as he faces a grand jury investigation.

Protester: “People are beyond angry, and we’re frustrated. We feel that three weeks later there’s been no actionable words. We don’t have an arrest. We don’t even really know why the officer has not been indicted.”

Among those who attended Saturday’s march was Rev. Raphael Warnock, senior pastor of Atlanta’s Ebenezer Baptist Church.

Rev. Raphael Warnock: “We are here today because while this is an issue that occurred in Ferguson, it really is emblematic of a national problem. The national problem being police brutality, the overpolicing of communities of color. Mike Brown died as a tragic casualty in an ongoing battle, it seems to me, for the soul of America.”

On Monday, a small group staged a symbolic action by blocking a state highway for several minutes, bringing traffic to a halt. A larger highway blockade was called off after a request from Michael Brown’s father. Organizers say they plan to hold another highway blockade at a later date in a bid for the appointment of a special prosecutor.
