Footage of student demonstrations at Columbia University in April 1968 from the Columbia Spectator. in April 2008 some alumni of Columbia held a reunion on campus called "Columbia 1968 and the world." See http://www.columbia1968.info/
I was the chairman of an elected committee of students from 21 schools of Columbia University that met with the University Trustees in the aftermath of the protests. I found out about the reunion by chance on the second day of the event. It sounded to me like a media event. Tom Hayden from California was one speaker. I'm not certain of his connection to Columbia.
This is a special response to questions from Lindsay Rhebb at Columbia Television.
