Ft. Hood shootings blame game continues

Major Nidal Hasan's behavior raised concerns long before he got to Fort Hood.

Doctors at Walter Reed Army Medical Center, where he trained, said he was belligerent, argumentative and defensive.

While they did not think he was violent, doctors said they discussed concerns about his overly zealous religious views and strange behavior. But because they were unfamiliar with his faith, doctors said they didn't want to unfairly single him out.

Instead, he was transferred to Fort Hood. Now, investigators say other red flags may have been overlooked for the same reason.

Months before the attack at Fort Hood, Hasan was already on the Department of Defense's radar.

Investigators said he reached out to a radical Muslim imam overseas. But some say political correctness prevented them from taking action.

"Hasan acted on his own, but he was motivated from radical jihadism. I think you can see this from who he was in contact with, the things that he said." Rep. Pete Hoekstra (R-MI) said.

Congress is now demanding answers and wondering what warning signs the military may have missed.

"I believe it was an act of terror." Senator John McCain (R-AZ) said.

"I want to thank John McCain, for calling this what it is," WFLA radio host Todd "MJ" Schnitt said.

On talk radio, phone lines are jammed.

"This whole political correctness thing, I think what's happening is that people are afraid to speak up," one caller said.

"There were red flags. There were lights. There were sirens," Schnitt said. "This is a classic case of what the hell went wrong?"

Last week's shooting rampage left 13 dead and 29 wounded.

While Hasan is now accused of the deadliest attack on a U.S. base, investigators still don't know why.

"He obviously has committed a terrible and heinous and violent act. Whether it's an act of terrorism or not is another thing." U.S. Army Col. (Ret.) Mike Pheneger said.

Pheneger served as the Director of Intelligence at U.S. Central Command, and said terrorists make their motives clear, often claiming responsibility.

"That's how terrorism operates. They normally want credit on behalf of whatever cause their acting for," Pheneger explained. "Hassan didn't do that. He may yet. But he hasn't yet. So it's very difficult to tell."

Whatever the motive, he believes more should've been done.

"This is one guy who apparently was behaving erratically in ways that came to the attention of somebody and the chain of command apparently didn't do anything about." Pheneger said.

Hasan still has not been formally charged. But officials are leaning toward trying him in a military court, rather than a civilian one.

If convicted, he could face the death penalty.
