I also notice that, when the madman went berserk, it was a holy place of a specific religion not his own that was attacked: he hadn't lost it to THAT degree. He passed churches to reach this place.
It is also significant what the madman's own religion WAS-- oops, it was the Religion of Peace[tm].
Still, one thing can be said: the majority of Muslims converting to Christianity in the last ten years in the USA were Pakistanis, probably because many of them had never really had much instruction or been practicing Islam very seriously in the first place. This Ali would appear to be a prime candidate: I will just betcha he hasn't seen the inside of a mosque since he reached the USA.
