He was being tracked by the FBI for the last 6 months because of sympathetic postings on messages board(s) about suicide bombings. Even if he was angry about being name called, as reported. Even if he was scared of being deployed, as reported. Even if he was desperate about getting out of the military and hired a lawyer to help him, as reported.I'm going to guess that he had some kind of jihadist issues going on in that head of his. I don't think it's racist or anti-Muslim to say that it's not a surprise that it was a Muslim extremist who did this. It's the world we live in. Extremists are extremist. The people who should be THE MOST angry here are moderate Muslims. Rather than downplay the Muslim side of it and get overly defensive, moderate Muslims around the world need to become far more vocal and ACTIVE about the reality of the direction of Islam. It's been hijacked by a specific sect. Moderate Muslims better figure out how to crush it because especially in the U.S. and the UK, non-Muslims are going to become very vigilante about these things, with moderates on all sides getting sucked into a cycle of violence.My 2 cents.
