They have a mountain of data already -- if they can't get a sense of what's going on from that then maybe they're not up to the task.
<snark> Slightly tangential anecdata: the FBI was warned about the suspicious flight school students yet they bungled the job of stopping the 9/11 attack. So what good is this comprehensive intelligence gathering if the government can't even use it properly? </snark>

For a general idea of what the book goes into, you can see Soufan's profile in the New Yorker: http://www.newyorker.com/archive/2006/07/10/060710fa_fact_wr.... In the (Pulitzer Prize-winning) reporter's own words: "Soufan became America’s best chance to stop the attacks of September 11th.".
Well they're one of the world's major industrial powers and just a couple of generations ago they threatened to take over all of Europe.
So much of the outrage over NSA spying (abroad) is predicated on this foolish idea that we live in a time outside of history, that while the West may have spent the better part of the last millennium embroiled in warfare with each other, that our generation is the first to be so enlightened as to make that unthinkable.
