Still photographs are the most powerful weapons in the world. Words and pictures have a continuing struggle for primacy. In my mind, a person can write the best story in the world; but a photograph is absolute.

I'm not a great believer in the power of the moving image. A still image has greater lasting power.

I saw a man walk into my camera viewfinder from the left. He took a pistol out of his holster and raised it. I had no idea he would shoot. It was common to hold a pistol to the head of prisoners during questioning. So I prepared to make that picture - the threat, the interrogation. But it didn't happen. The man just pulled a pistol out of his holster, raised it to the VC's head and shot him in the temple. I made a picture at the same time.
