On this day, the 1st of February in 1968, a very famous photograph was taken in South Vietnam. Probably the most iconic photo of the Vietnam War, even more so than the My Lai photo.
What photograph am I speaking of?
On this day, the chief of police in Saigon, Nguyen Ngoc Loan, executed a captured Viet Cong officer with a pistol shot to the head. For those of you who don't know, there is no real debate about who the man getting shot was. He was captured fighting in civilian clothes, and was by definition, a spy and saboteur.
