Jesse Williams joins Ferguson protest rally

Grey'S Anatomy star Jesse Williams was one of the thousands who rallied in Missouri over the weekend (ends12Oct14) seeking justice for the the killing of unarmed teenager Michael Brown.

In August (14), race riots between locals and law enforcement officials in Ferguson erupted after Brown, an 18-year-old African-American, was shot and killed by a white police officer investigating a robbery.

While a grand jury is still meeting to decide whether the cop who killed Brown will be charged, thousands of citizens gathered in Ferguson on Friday for "Ferguson October", a planned weekend of four-day protests.

Williams joined in on Saturday (11Oct14) as they marched 12 miles from Ferguson to nearby St. Louis, demanding the officer under trial be charged with a crime.

The actor documented his weekend on his various social media accounts, posting photos of himself talking to protesters and in the thick of the crowd's march to St. Louis.

One photo, showing Williams giving comfort to a distraught female protester, was posted alongside the caption, "This is a two way street. Ferguson, MO Oct 11, 2014."

Williams is also part of the Question Bridge: Black Males video project team, which is documenting Ferguson October to "archiving the thoughts and concerns of the people and recording Black males asking and answering the questions that matter to them," according to his Tumblr page.

Williams isn't the only celebrity in town to show support for the protests - artists such as Talib Kweli, dead prez, and Jasiri X performed at a free Hip Hop 4 Justice concert on Sunday (12Oct14).
