"We are trained to look for things other people don't look for," Sal Veder said.
Veder calls it a gift. In 1974 he won the Pulitzer Prize for a photo of Lt. Colonel Robert Stirm coming home from Vietnam after five years as a prisoner of war. Veder never learned the back story until much later; Stirm's wife had filed for divorce that very day.
