Apparently, it's not the abuse that's the problem, it's the photos of it.
I'm with Clarence Page:
If I had my way, every enlisted man and woman in the military would be issued a digital camera. As we've seen in the scandal about abused Iraqi prisoners, the little gadgets help boost morale by providing snapshots that can be e-mailed back home. They also can come in handy when you need to gather evidence. I like those little cameras because certain power elites don't.Apparently, Rumsfeld lives in Topsy Turvy World. You know: where right is wrong and wrong is right?
What's the bet in their next war the administration figures embedded journalists ain't such a good idea, either? Now that one they probably won't get away with. Once the press has had access, they're not too happy about giving it up.
Update: I believe it's since been proven that Rumsfeld did not ban camera phones. Nonetheless, the quotes attributed to him lamenting the use of cameras on the battlefield were quite legit.
