Why Am I Not Surprised?

"Assassins never vary their methods" -- Security Chief Odo from the Star Trek Deep Space Nine episode "Improbable Cause"

Remember how incriminating documents left conveniently lying around allowed the authorities to quickly identify the supposed 9-11 hijackers within 48 hours?

Keeping that in mind, I more or less expected there to be documents left behind in London which would allow the authorities to quckly identify the supposed bombers.

And, sure enough:

"Police found a bomb factory in Leeds containing a “viable amount of explosives”. Explosives were also recovered from a car left parked near Luton station. The raids came after the discovery of driving licences and credit cards at the scenes of the explosions, and a telephone call from the mother of Hasib Hussain, who asked police to try to trace her son. "

Damned convenient, huh?
