Morris uses The Interrortron to interview the subjects of the movie.
Fascinating essay by Morris here on the film:

"There's one photo that endlessly fascinates me. It's Sabrina Harman with her thumb up smiling over the corpse of an Iraqi prisoner. I looked at the photo and thought, initially, what a monster. I now know she had nothing whatsoever to do with this man's death and she was secretly taking photographs to prove that a murder had occurred and the U.S. military was attempting to cover it up. In fact the picture means something much closer to the opposite of what we think it means."
