Goathead,
It's destruction of Govt property for starters. And 2nd, it presents a negative image towards the US military. For commanders and Senior NCOs to allow something like this would demonstrate a form of acceptance or support by the DoD in presenting such an image or statement.
"Iraqi Photos" implies all Iraqi citizens. The unfortunate side of something like this is how it can turn on the military and present a very negative image. This is the type of propaganda that the insurgents would love to spread, and to see us spreading it in celebration or approval only further enables them to spread the message that we are there not for the advancement of their country, but for further destroying their culture and way of life.
It's a lose/lose situation either way. Not trying to stand on a soapbox, but acts like this make all of us look bad.
Just my $.02
