A New York City police officer stands guard over the official 9/11 National flag at the Russell Senate Office Building in Washington, D.C., on Thursday, July 14, 2011. The flag was in the nation's capital for a stitching ceremony in which members of Congress, 9/11 families, first responders and the general public were all invited to add stitches to help complete the flag. This flag was flying just south of the World Trade Center on Sept. 11, 2001 and is now being stitched back together by Americans from across the country, many of whom have suffered tragedies of their own. Where pieces are missing, people are adding their own pieces, including entire flags and a piece of the flag that cradled Pres. Abraham Lincoln after he was shot. (Barbara L.
