Seems as if they knew of Officer Nidal Malik Hasan's radical internet postings 6 months ago. Years ago one of my Federal Officer co-workers who was Muslim showed me a little green book he had titled "Jihad". At the time i didnt know what the heck the word meant. In any case he died of liver disease.
Perhaps it's time for stricter controls of military personnel, and not letting people who have shown tendencies towards extremist ideals, be it christian extremists, jewish extremists or muslims extremists, not be granted the ability to work in the military, or any form of law-enforcement/security agency?
I mean if I saw a soldier under my command posting on a christian website saying that "Arabs are animals and all arabs and muslims should be killed", and vice versa, I sure would take this up with my superiors and recommend they discharge him.
