I knew a minister who was getting his Mdiv at Harvard in the late 60s.
He told the story of being taken in by protestors prior to the occupation of a building, and how the leader– a rich kid who drove an expensive sports car– ran out the back door the minute it looked like anyone was going to get in trouble.
This minister said the lesson affected him profoundly and had lasted his whole life. Very few protestors were there on principle; most liked to make mischief, and let others take the heat.
