If you're after some reading, Film Crit Hulk has posted about Spike Lee's Do The Right Thing and how it relates to Ferguson. Good stuff about co-opting the Ferguson message as well as what we can learn from Spike Lee's classic. As with anything Film Crit Hulk writes, it is written Hulk-style (all caps), so YMMV.
(Note: I adore Film Crit Hulk! He is a friend of a friend and a pleasure to read! Also I adore Do The Right Thing, which I have been thinking needs a rewatch right about now. So much of what is happening in Ferguson right now plays out on the hottest day of summer, 25 years ago.)
