It is hard to understand unless you lived through it. I was in the center of the action during those times when I was attending George Washington University. The Police had come into our campus and it was chaos. I and a friend who had attended or attempted to attend one of the marches in May 1970 hid out in one of the classroom buildings because the campus was full of tear gas and the CDU (DC Police's Civil Defense Unit; not people we loved) were on campus and not in a great mood, as you might imagine. The demonstrations had started after early morning classes has begun and when students from one of those classes walked out of their building (not realizing what was taking place), they were all arrested and sent to central booking. It was quite a scene. Eventually all charges were dropped.
