Six weeks after Gabrielle Giffords was shot, her doctor tells CBS New that she’s making remarkable progress and interacting with friends and family, but she still doesn’t know exactly what happened to her. “She certainly knows that there’s been a traumatic event here,” said Pia Carusone, Giffords’ chief of staff. “The details of the severity of the injuries to the others, you know, she doesn’t know yet about. But she will in time, when she’s, you know, at a higher level of communication. Doctors have said it’s not really fair, as you can imagine, to tell something so tragic to someone that might not have the ability to ask the detailed questions that someone will have when they hear this news.”
