Tensions had temporarily cooled on Thursday night but by Friday evening, protesters were again swarming through a residential and retail district in the small town outside St. Louis that has become the site of repeated clashes between protestors and police forces. The unrest erupted after Ferguson police officer Darren Wilson, 28, shot and killed Brown shortly after noon last Saturday as Brown and a friend walked down a street that runs through an apartment complex where Brown's grandmother lives.
