After the rally, we witnessed a near-street riot involving the exiting McCain crowd and two Cuban-American Obama supporters. Tony Garcia, 63, and Raul Sorando, 31, were suddenly surrounded by an angry mob. There is a moment in a crowd when something goes from mere yelling to a feeling of danger, and that's what we witnessed. As photographers and police raced to the scene, the crowd elevated from stable to fast-moving scrum, and the two men were surrounded on all sides as we raced to the circle.
