Official: Hasan's Coworkers Had Concerns

Fellow medical residents of army psychiatrist Maj. Nadil Malik Hasan, the suspect in the shooting rampage at Fort Hood, had concerns that he wasn't a good candidate as a physician and they were concerned that he was proselytizing, or preaching his Islamic faith to patients, a U.S. Defense official told CBS News correspondent Kimberly Dozier.

"The concerns were raised to higher levels of management at Walter Reed," he said. "But people who reviewed his case did not see his performance as so poor that he needed to be kicked out of the residency program," the official told Dozier. "And you've got to remember, those discussions happen in every residency class. You will always have one out of five that isn't measuring up - so Hasan-as-problem-case was standard that way."

The official, who spoke on condition of anonymity, could not confirm that someone at the Walter Reed Army Medical Center thought Hasan was psychotic.

"But trying to prove that someone's psychotic is very difficult," he said. "When someone is really intelligent, but may be only mildly psychotic, particularly when they are trained … it's hard to spot. A trained psychiatrist knows the answers to give to throw people off."

The official said that many of Hasan's former colleagues were crushed by what happened.

"Before people leap to judgment and judge them as not stopping this person, just understand, they're not mind readers or magicians, and in some cases, you just don't know what's going to happen in the mind of the individual," he said.
