struggling and scrambling to deal with right now, shep. al qaeda has changed its strategy moving away from the big 9/11 style attacks. more to sending out, if you like, freelance operatives, hundreds, if not thousands of extremists told to go out to plot and plan their own attacks and to act when the opportunity arises and when they feel they are ready to do so, rather than awaiting orders from al qaeda leadership. listen now to our own national security analyst k.t. mcfarland. the new wave is individual bombers. couple of people doing small scale stuff. go to the local fertilizer store, get the stuff, make it all yourself. go to the local subway station and blow yourself up. those kind of attacks, shep, are not only difficult to detect, but extremely difficult to defend against. shepard: as it turns out, the latest british arrest appear to be related to that sort of attack. exactly, shep. a dozen men between the age of 17 and 28.
