I've heard a lot of stuff in the last two weeks about X telling the CIA or FBI this that or the other thing. And while, after the fact, they all plainly related to this plot I have yet to see anything that would have given enough info about this plot BEFORE the fact to allow anyone to stop it. It's the old "5 W's" of journalism (who, what, where, when, why and how), obviously the CTC could give a damn about why, but if you can't give them at least two of the other four (and again, who is the workers not the mastermind) you can't expect them to stop anything. And none of these supposed tips even included one of the W's.
