I think they got the info out of Rauf in Pakistan. Maybe they even tortured him. No offense to the Brits meant. The copoperation and coordination is outstandiong and encouraging imho.
The question is, how many plots like this are going on where nobody's come forward with a tip for them.
Reid, the cop in charge or minister or something, said they have 70 PRIORITY terror investigations going on currently. And that's only the ones they know about and think have a high probability of success.
Ye gods only know how many they don't know about, but it's a lot.
Well, I"m off to bed. nite ;)
