The article says Hinrichs lived at Parkview Apartments, just a few blocks from the mosque of the Islamic Society of Norman. Also fueling the link to some kind of Middle East terrorism is the fact that Hinrichs' roommate, Fazil Cheema, is from Pakistan. Acquaintances of Cheema's say he is not a practicing Muslim and never attends services at the mosque.
But I just watched a very good movie produced by BBC titled
" Dirty War" which though fiction was based on actual intelligence research. One of the points made was that the bombers in the movie DID NOT ATTEND MOSQUE. So I would not put too much stock in the fact Cheema did not go to Mosque. Very possibly they do not want to be seen as extremists and draw attention to themselves.
