LA JARA, Colo. — The photograph, of four popular high school students standing side by side, each clutching a gun in one hand and giving a stiff-armed Nazi salute with the other, terrified many people in La Jara and the surrounding poor farming communities of the San Luis Valley. Its discovery further intensified a bitter racial divide between supporters of a longtime coach, who is black, and a largely white group of students and their parents.
