"TUCSON - On the second floor of the intensive-care unit, behind a phalanx of police officers and a shuttered glass door, they sit by her bed all day and night, a rotating circle that includes her husband, her mother and father, her chief of staff, and her rabbi.
"They talk to Rep. Gabrielle Giffords, hoping she can comprehend what they are saying. They take note of every movement of her fingers and legs. They celebrate when she opens her eyes. They sing and pray. They weep.
"From the moment a gunman critically wounded Giffords, this city has held a 24-hour-a-day vigil for the six people killed and 13 injured in Saturday's spasm of violence. A shrine of floral bouquets and candles expands by the day, enveloping the entrance to University Medical Center."
