So lets run the plan
Al Qaeda plans a terrorist CYBER attack to get back at those drones that kill hundreds in Pakistan.
Osama: "We need to show these decadent capitalist pigs that they cannot use drones to kill our people!"
Mustafah: "Why are you speaking like a cold war clique Osama?"
Osama: "Never mind that, we will hack into Mango's supply computers and place an order for the Chipping Norton branch to receive all *Summer* clothes in the middle of *Winter*!"
Mustafa: "Devilishly clever, when the westeners see the stylish yet unsuitable clothing, they will purchase it and freeze to death!"
Osama: "Exactly, that will show them".
Meanwhile in GCHQ, ten thousands servers monitoring all communications into and out of the UK notice that a Mango Chipping Norton's Internet is being probed.
Dudly Dooright: "Quick call the Prime Minister, Mango's Chipping Norton Branch is central to the UK economy, we must protect it at all cost or people will die! DIE I SAY! We must send millions of packets or they will never be able to get their order for winter legins through!"
Prime Minister: "But how can you tell it's an attack"
Dudly Dooright: "Because all other internet traffic surfs for porn, BTW, tell Alistair Darling to approve our budget, tell him 'flat chested midgets in leather" think its a good idea..."
Yep, that sounds right, nothing to do with the Internet Mass Surveillance program (IMP), absolutely nothing at all, our High Street stores face the threat of AlQaeda cyber attack and hence we need to protect them from, erm, terrorists thingamibobs. THE THREAT IS REAL!
