Who's responsible for the picture/blackmail policy?

I was having some trouble understanding why people would take photographs of their mis-deeds. Yes, some warped types would take photos to brag on, but mostly people don't want evidence of their sins wandering through the world.

Scenario: Someone is somewhere in Iraq trying to get "support" for the "new democracy" created by the U.S. You've got some recalcitrant locals, maybe some of these obstinate types are even in the Iraqi police. What better way to convert them to happy citizens of our "big rock candy mountain" client state than to threaten them with the most embarassing images possible. "Pssst, hey Ahmed, you know Muhamar? You know why he won't cooperate with your political group? He's a pervert! A friend of mine surprised him in prison one night. My buddy happened to have a camera and he got photos. Believe me Muhamar and his friends are sexual perverts."

to use against the prisoners for further humiliation.

i think who is leaking and blackmailing rummy are generals and others in the pentagon. just a guess
