Second, from the artilce posted abve:
Starting in the spring of 2008, key officials from Walter Reed Army Medical Center and the Uniformed Services University of the Health Sciences held a series of meetings and conversations, in part about Maj. Nidal Hasan, the man accused of killing 13 people and wounding dozens of others last week during a shooting spree at Fort Hood. One of the questions they pondered: Was Hasan psychotic?
“Put it this way,” says one official familiar with the conversations that took place. “Everybody felt that if you were deployed to Iraq or Afghanistan, you would not want Nidal Hasan in your foxhole.”
So why didn’t officials act on their concerns and seek to remove Hasan from his duties, or at least order him to receive a mental health evaluation? Interviews with these officials suggest that a chain of unrelated events and factors deterred them.
For one thing, Walter Reed and most medical institutions have a cumbersome and lengthy process for expelling doctors, involving hearings and potential legal battles. As a result, sources say, key decision-makers decided it would be too difficult, if not unfeasible, to put Hasan on probation and possibly expel him from the program. . . . . .
From the article:
It can't be any cheesier to say that the reason Hasan successfully launched his attack, is because he was drummed out of the service for being a substandard officer.some of Hasan’s supervisors and instructors had told colleagues that they repeatedly bent over backward to support and encourage him, because they didn’t have clear evidence that he was unstable, and they worried they might be “discriminating” against Hasan because of his seemingly extremist Islamic beliefs.
I certainly hope that that's not going to be what we depend on to weed out ptentially dangerous service members.
