Same here. I was at Northeastern University in Boston during the 1970 Cambodia rioting. One night I was waiting out in front of the school at the trolley stop on Huntington Avenue after a few hours at the library when a small crowd of SDS provocateurs and their supporters fled by my toward their Hemenway Street refuge. Close behind was a pursuing crowd of Tactical Police Force cops in hot pursuit. My long hair, pea coat and camouflage pants apparently qualified me as a legitimate law enforcement target, despite my armful of books. I was clubbed to the ground by a passing cop.
It happens.
We had some of our college slum parties at Youngstown State (GO PENGUINS!) raided by police. A little tear gas shut things down without much incident. You know you had a good party when you can still smell the tear gas in the morning. (that was a long time ago soon after the invention of colleges)
