Call it what you want. Baghdad is a city under heavy military guard. They may not patrol the streets as they used to but they are waiting in the wings when the trouble flairs. Wait until all the troops pull out of Iraq and the militia retake their own localitys again. They know they cant out gun the U.S. & British army so they'll bide their time and then help themselves to the armour and weapons as soon as they're gone. U.S. & U.K. governments will harp on about power being handed over and mass troop withdrawls within the net few months but this is political spin. Foreign influenence and presence will always be in the shadows, similiar to the U.S. involvement in Vietnam.
Statistics have shown and indeed news headlines boast Baghdads crime rate has significantly decreased but this must be taken in to context with the high level it was at and the presence of foreign occupational forces today.
Foreign security contractors operate with impugnity and face little if any repercussions for "protecting themselves".
