In 1969, Chicago was home to one of history’s most high-profile trials. Known as the Trial of the Chicago 8 — and sometimes the Trial of the Chicago 7 — the trial pitted anti-war protesters against the federal government. Eight men were accused of conspiring to incite a riot during protests that took place in Chicago during the Democratic National Convention of 1968. Outside the courtroom, protesters and onlookers gathered. Some chanted to free the men. Some came with signs and posters of protest and solidarity. In this episode, reporter Arionne Nettles explores the intersection of art and protest movements as she tries to track down the artist behind one of these posters.
