A man walks through the crowd at the Ground Zero protest and is mistaken as a Muslim. The crowd turns on him and confronts him. The man in the blue hard hat calls him a coward and tries to fight him. The tall man who I think was one of the organizers tried to get between the two men. Later I caught up with the man who's name is Kenny. He is a Union carpenter who works at Ground Zero. We discussed what a scary moment that was for him. I told him that I hoped it did not ruin his day.
