Excerpt:
A security expert who contributed to a now-classified 2008 study aimed at helping military officials recognize the signs of extremism among troops said it could have helped prevent the shootings at Fort Hood, Texas.
Shannen Rossmiller is angry that the study she worked with the Pentagon to create -- unclassified at its inception -- is now under wraps. She told CNN she is concerned political correctness trumped the study. As a result, she said, it failed to serve its intended purpose -- to help military officials recognize the signs that one of their own might pose a threat.
"These people didn't have to die, and that's why I'm speaking out," Rossmiller said.
CNN contacted the Pentagon about the report, but officials there did not immediate react to it.
