When I heard his roommate was Pakistani, red flags went up all over the place. It seem like the fruits of infiltration are starting to pay themselves off if anything can be concluded from a college student trying to pull something like this off. Grey terror just went up a notch or two.
I also think that as a nation, we've been fairly blind to the ISI's operations. The ISI must have assets embeded amongst many of the Pakistani student cliques in the US (and UK).
