Why do we insist on ignoring what stares us in the face? The suicidal fanatics who threaten to kill us in the name of their perverted brand of Islam are not refugees from Syria, or deranged zealots from the mountains of Pakistan: they are, with only very few exceptions, men and women who were born in our hospitals, educated in our schools and who grew up in our cities... Many of the attackers were already known to the police. Some had records as petty criminals. Others had clear links to identifiable terrorist groups. So as we still struggle to comprehend the crime that was committed in Paris last Friday night, perhaps we should start by examining what is going on under our noses.
