Friends and families of terrorists don't know anything?

With his usual great attention to detail, Victor Davis Hanson documents in National Review about how, after horrendous terror attacks like San Bernardino, the Boston Marathon, 9-11, and Fort Hood, we learn that family and friends of the killers were well aware of the radicalization of the terrorists, but did nothing to stop them.

In almost all of these cases there is a monotonous narrative. Muslims arrive from abroad, often citing dangers at home and new opportunities in America. They are treated well, frequently being offered public assistance, university admittance, scholarships, or government jobs. Their children become “radicalized.” (Note that this is a passive term rather than an active one — as if mysterious forces rather than free will turn someone into a killer.)

It seems inconceivable that family members could be oblivious to the radicalization of a loved one when it transpires right under their noses — particularly in the cases where a parent’s U.S.-born children visit the Middle East and come back radicalized, with the change noted by friends but supposedly not by immediate family. The idea that close relatives do not know about the Islamic extremism of their kin is as absurd as it is dangerous to the security of the United States.
