From the article:
"NEW ORLEANS, Sept. 8 - Local police officers began confiscating weapons from civilians in preparation for a forced evacuation of the last holdouts still living here, as President Bush steeled the nation for the grisly scenes of recovering the dead that will unfold in coming days. Police officers and federal law enforcement agents scoured the city carrying assault rifles seeking residents who have holed up to avoid forcible eviction, as well as those who are still considering evacuating voluntarily to escape the city's putrid waters."
