I think using alcohol and frequenting strip clubs are also verboten, aren't they, but that didn't stop some of the 9-11 loons. Maybe, if this guy was an Islamist, living with an infidel is part of the cover.
The drinking alcohol and going to strip clubs is a standard pre-suicide mission SOP, going back to the days of Muhammed and Ali. In the old days, it was hashish, wine and harem girls. It gives the soon-to-be "martyrs" a foretaste of paradise, where the rivers run with wine, you get 72 virgins to rape at will etc. That's how you get these moonbats to push the trigger button with a great big grin on their faces. They are sure one second later, they will meet allah and collect their "reward."
True, but if I were looking for cover in that manner, I would also not be living in what amounted to the "Pakistani section" of the campus.
