As forces of an occupying power they should urgently take measures to enforce law and order in the areas under their control, specifically by preventing acts of pillage, destruction, and violence to persons

I have to agree with that one. Too bad the US forces wouldn't allow the civilians of Fallujah to leave before they started bombing it (they "claimed" that there were no civilians there at the time... obviously the bodies of the dead families tell a different story). Since they did not take this measure to protect the civilian population of Fallujah before they started shelling, the US forces and the US government are in violation of this part of the UN mandate as well.
