Am I bovvered?

Well the Head of MI5 certainly laid out a disturbing picture in a speech last week - 30 known terror plots, some 200 terrorist groups operating, 1600 individuals under observation. Pretty scary, no? Well, perhaps, but you need to bear in mind that this is part of the same intelligence service which (so we were told) was sure that Iraq had weapons of mass destruction, and the same intelligence service which has to take its share of the responsibility for the tragic Stockwell shooting and the massive high-profile raid on a house where it was convinced a chemical explosive device of some sort was being constructed but where, in the event, nothing was found. So let's be concerned, but keep our feet on the ground - OK??
