It is surprisng that everyone is saying what a shy and decent guy this man is / was as he knew him. Without prejudice, I would only say that infiltrators do not go about wearing badges or with blazing tattoos proclaiming their purpose. Behring, one of the best German operatives who was instrumental in ferreting out and passing along info that helped German subs destroy the important Royal Navy base of Scapa Flow had mingled with the local populace for few years and was considered a worthy patriotic citizen. He quietly slipped out to Germany too and was duly felicitated by Admiral Canaris, his spymaster.
We must realise that these secret agents are human beings too and in all probability also love their families, and thus would not like them to come to any harm; so the less they know the better. Also, in many communities, women are not encouraged to ask their husbands too much about what they do to earn their livelihoods, so they being ignorant about the husbands' activities is an acceptable possibility.
The Haneef family's reaction that he was targetted because he was a Muslim seems too stereotyped, though. He wasn't the only Muslim around, so many of them around, why was he caught? Just because he was a Muslim? What about the other few thousand Muslims living in the same city? Sorry folks, yeh baat kuch hajam nahi hui!
