Bergen: Missed warning signs of terror attacks?

CNN's Peter Bergen analyzed why the Boston bombings -- and 9/11, for that matter -- weren't prevented, but it's the very end of his story that caught my eye:

The problem is that, as Roberta Wohlstetter pointed out half a century ago in her study of Pearl Harbor, separating out the really important signals from all the "noise" in the system is only easy to do after the fact, particularly when the U.S. government has now assembled a database of an astonishing number of 700,000 individuals it suspects of ties to terrorism.

Bergen is trying to compare the Pearl Harbor surprise attack to terrorist attacks. But there's a big difference: there weren't 700,000 Japans to keep track of in 1941. Presumably, any one of these suspects could carry out an terror attack today... or somebody who is not on the list at all.

Still, it's hard to believe there are 700,000 people in the world with ties to terrorism. Shouldn't there be way more terrorist attacks if there are so many of them?

More likely, this data base of suspects is another out-of-control government program.  Maybe we missed the Boston bombers because we were too busy following around 700,000 other people, many of whom didn't deserve to be on that list?

UPDATE (05.06.2013): Here's another article about America's bloated terrorist data bases: "Terror database too unwieldy to flag Boston suspect, critics say." The Terrorist Identities Datamart Environment (TIDE) list, with 875,000 records, is the big daddy from which all other government data bases draw, such as the FBI's Terrorist Screening Database, which in turn feeds the State Department's watch list, which is supposed to prevent terrorist suspects from getting U.S. visas.

Agencies often miss warning signs of attacks
