The Fort Hood Tragedy--could it have been stopped?

I received a welcome e-mail from my New York City online English as a Second Language science researcher student yesterday wishing me a happy Veterans'Day. Actually, the truth was I had forgotten that it was Veterans' Day. However, it got me thinking back to my time in the service and what I might be doing now if I were in the Army and stationed in Texas. I am sure that I would be right in the middle of this Fort Hood disaster because I was an Army investigator with the Counter Intelligence Corps. I have been reading about this Major Hasan and wondering how in the world he got as far as he did! It made me think back to the World Trade Center disaster and in that case it was an agent in the field who practically SCREAMED at her superiors that there was something wrong. Those that eventually flew those two planes into the two towers of the World Trade Center were taking flying lessons but they made it clear that THEY WERE NOT INTERESTED IN KNOWING HOW TO LAND AN AIRPLANE!. I believe this was an agent in the Minneapolis FBI Field Office. The agent's report must have gone up the line to an analyst somewhere (perhaps in Washington) where it was deemed unimportant or simply ignored. The results were catastrophic. In the Fort Hood case, it was known that Major Hasan was in communication with a radical cleric in Yemen for some time. The FBI most likely had all of his external communication under watch. This would mean a mail cover, phone tap,etc.
There is that old cliche that fits in this case perfectly: "Hindsight is always 20/20. This major should have been taken into custody as soon as he purchased the gun in the civilian gunshop. How were authorities to know that? They had enough knowledge about him to put him under surveillance. Surreptitious surrveillance on a military post would be very difficult to maintain. However, a "controlled surveillance" where the subject knows he is being watched was in order. This man was not acting rationally and it is possible that he just might have tried to buy a gun even under surveillance. It is too late now. What we have to be careful of now are the haters and those who would stereotype ALL muslims as terrorists. That makes it even worse. We have to be careful, yes, but I will still think about that wonderful student, KHADIDJA, who taught a whole class of ESL students the meaning of DIGNITY when it comes to the Moslem religion, before I listen to those screamers of hate.
