Unfolding details on Fort Hood shooting

New details are emerging this morning out of Fort Hood, in Texas, where an army psychiatrist has allegedly killed 13 people and injured 31 during a shooting rampage. Major Nidal Malik Hasan is alive but injured after being shot by a civilian officer. We’re joined by Ericka Aguilar, KUT reporter in Fort Hood. Matthew Cassese was stationed at Fort Hood in 2007 and 2008. He remembers a base that was safe, but says soldiers were frequently in trouble for drunken driving. We also talk to Detective First Grade Nick Casale, a former director of counterterrorism for New York City’s subway system, about what is involved in a complex criminal investigation.
