When I arrived in Baghdad, after spending a month in southern Iraq, it was still possible to go out on your own without security personnel. First I took a look at the local hospital and after spending some time there I strolled around the premises of the hospital. I stumbled upon a group of Marines who were securing the buildings around the hospital and looking for possible collaborators and or Iraqi soldiers/snipers hiding in the high rises next to the hospital. The Marines were searching the buildings thoroughly and opening each and every room by kicking in the doors.”
