A press conference at Fort Hood Army Base in Texas answers some of the questions stemming from yesterday's tragic shooting on the base. Major Nidal Malik Hasan, an army psychiatrist, is suspected of gunning down his colleagues, killing 13 and wounding at least 30. Officials say Hasan walked into a military compound with two guns and opened fire yesterday afternoon. He was shot and is in critical condition. We also speak with Dr. Brian Aldred, the medical director at the Emergency Center at the Seton Hospital near Fort Hood, Texas, about his hospital's response to the tragedy. Finally, we speak with Olga Pena, the managing editor of the Killeen Daily Herald, who has been following this story.
