A rough-and-ready and, if memory serves, heroic piece of radical agitprop produced by Newsreel in 1969 about a student strike at Columbia over the University’s policy toward the surrounding community of Harlem. On the same program, two 25-minute Newsreel documentaries of the same year, San Francisco State: On Strike and People’s Park. For a genuine whiff of this era, you probably couldn’t do much better.
