If you look around blogs anytime these last few days, someone somewhere is writing about the bombs which went off in the Tubes and one which detonated on the top level of a double decker bus.
They're working on it. What the people who are behind this fail to realize is that 1) stiff upper lip means not giving in to fear 2) Scotland Yard, considered to be the best in the world when it comes to police work, is in THAT country and 3) due to security cameras just about everywhere, footage is bound to come up of the ones responsible.
Hmm.. let's see, can we say lack of foresight?
As for Al Quieda, jury still out. Have the feeling, though, enough potential terrorists live in London to not need outside help. "Claiming" to be AQ is a far cry from having memebrship. Ever heard of the term wanna be?
