Doctor who treated Fort Hood Victims: We are not just concerned about their physical state, but also their emotional state

Ivan Lopez took three lives before taking his own. He also wounded 16 others. Some of them were rushed to Scott and White Memorial Hospital. Dr. Matthew Davis is the Director of Trauma there, and he treated some of the shooting victims.  Dr. Davis also treated the victims after the 2009 Fort Hood shooting. He spoke to John Berman about his team's response to the shooting.
