Today Associated Press reports the massacre of civilians at Haditha in the Anbar province is worse than Abu Gharib:

The shootings last November at Haditha, a city in the Anbar province of western Iraq that has been plagued by insurgents, were covered up, said Rep. John Murtha…"Who covered it up, why did they cover it up, why did they wait so long?" Murtha said on "This Week" on ABC.

"We don't know how far it goes. It goes right up the chain of command….I will not excuse murder, and this is what happened," Murtha said. "This investigation should have been over two or three weeks afterward and it should have been made public and people should have been held responsible for it."
