Not a trivial point.
The U.S. military is well-known for preparing after action reports and lessons learned. So let's hope they study this incident and learn from it -- just as they would from a regular "battlefield" engagement.
If they do so, perhaps there's reason to hope the next jihadi-in-uniform who tries something like this will be rushed and tackled after his first shot.
(And let's have no doubt: There will be other such incidents.)
Even though it was a well known fact, I was surprised and shocked to learn the soldiers on Ft Hood are not armed. I just assumed they were all armed.
The deer in the headlight comment bothered me. It suggests (to me anyway) that each person in that room was paralyzed by fear.
Suggesting what the Army should do to make sure this never happens again is fine and fair game.
