Jason Burke’s investigation into “home grown” terrorism in the UK. On the net in two parts. His title was: “Omar was a normal British teenager who loved his little brother and Man Utd. So why at 24 did he plan to blow up a nightclub in central London?”

The article argues many things: the role of the radical mosque has been exaggerated; the average age of individuals is 29, older than commonly thought; and images from the mainstream media are as important as “terrorist propaganda ” in radicalisation. Worth a read. Burke is European editor of the Observer and a respected journalist.
