I am one of the two people who were at the second corner where this angry young man confronted us. Years ago in California I participated in psychodramas where those who chose to do so outlined a difficult interpersonal relationship and then others present would role play to give the central person a chance to review through interpersonal psychodrama the issues of concern. To me this man was having a psychodrama and we were the ones to whom he could direct his anger. I did feel sorry for him. I hope we or someone else can continue talking with him and allow him to express what he feels as it only by seeing and accepting what you feel and then trying to see why you feel that way that you can grow through a psychological nightmare and I do think his experience was such. He asked me, "Oh so you think my friend's died for nothing?" And I was honest and said, "Yes."
