University of Maryland students held a rally 5/4 protesting U.S. involvement in Cambodia and "the indiscriminate use of noxious gas" by police at an earlier demonstration. This unidentified student was knocked to the ground by a car attempting to get through the crowd of students when they began marching and blocking a major highway which runs through the campus.
