The muzzies are not as stupid as everyone believes, dont know if he was a muzzie or not but they will start using WASP looking people to do their work. I don't think this was a prank gone bad as some have suggested, nor was it an experiment unless you count how many infidels can I kill as an experiment.
I don't think anyone really thinks it was a prank. However, the speculation over the muslim origins is now getting mindless. There are muslim terrorists, agreed. However, it seems that too many on FR seem to have forgotten that Klebolds and Harris's walk among us as well, and they can be just as deadly.
