This is starting to look more and more as if it could have been an attempted jihad "martyrdom operation."

Here's an excellent [1] video link (thanks to Steve) to an Oklahoma news story on how Joel Henry Hinrichs tried to buy the same fertilizer used in the 1995 Oklahoma City bombings, and attended a Norman mosque -- the same mosque attended by "twentieth hijacker" Zacarias Moussaoui. He also had a Pakistani roommate.
