NPR's Anne Garrels reports from Baghdad, where hundreds of civilians are cheering the arrival of U.S. troops. Garrels says the few journalists covering the war from inside Baghdad are breathing easier as Iraqi security officials seem to have completely disappeared. Looters target government offices, while civilians deface posters and other signs of Saddam Hussein's regime. "Something just snapped" among the Iraqi populace, Garrels says. Fighting is still reported in parts of the Iraqi capital — and in other parts of the country.
