A 50min documentary looking at students protesting on the Colombia campus.
From Wiki –
”The Columbia University protests of 1968 were among the many student demonstrations that occurred around the world in that year. The Columbia protests erupted over the spring of that year after students discovered links between the university and the institutional apparatus supporting the United States’ involvement in the Vietnam War, as well as their concern over an allegedly segregatory gymnasium to be constructed in the nearby Morningside Park. The protests resulted in the student occupation of many university buildings and their eventual violent removal by the New York City Police Department.”
