I use this image in my classes to explain how you can use photography to sway opinion. Bay Lop was in civilian clothes and, under the Geneva Conventions, was subject to summary execution as a spy. The general was perfectly within his rights to execute the prisoner.
Ugly? You bet. Horrible? No question. But this picture turned opinion against the Vietnam War literally overnight.
