Photoshop, epistemology, ethics, and war

Remember my little discussion of that Teresa Neilsen Hayden piece about trying to understand a deceptive infographic, and the work it took to follow the trail to find out its real agenda?

Terry Karney does something similar with a photograph used for propaganda favoring the Iraq War, tracing where the photo came from and the story that lies behind it. It's another fascinating exercise in the value of skeptically reading what you see.
