By the time I arrived at Madison in the fall of 1975, several of the conspirators in the bombing had been arrested and were being prosecuted. I had a knock on my door in the dormitory where I was living as a freshman, and it was some brain dead hippie who was raising money for the legal defense of David Fine, one of the conspirators. Two mistakes there, knocking on the door of a college student looking for a donation of any kind (I was very broke, all of the time then), and knocking on the door of someone who knew of and cared about the victim of that crime. I tore into that bastard and he left frightened by my response.
Fine was convicted, served time, attended the University of Oregon Law School and passed the bar there. He was rejected for admission to practice, and sued. Fortunately, he was never able to get licensed. He could not pass the moral character requirement.
Every August, in years that mark a 5 year anniversary increment - the local papers cover the topic with a "where are they now?" approach, focusing on the bombers, one of whom, Leo Burt, remains a fugitive. Very little is ever said about the victim.
