US "Fusion Centers" For Intelligence Sharing
Wired has an article on the national fusion centers in the US, which were created to aid intelligence-sharing in the fight against terrorism but are increasingly being used to look at other sorts of crimes. The keynote of these centers is "all hazards, all threats" — the LA police chief is quoted: "Information that might seem innocuous may have some connection to terrorism." The ACLU has up an interactive US map to help you become acquainted with your local fusion center.
In other words, these are data mining centers, designed to organize and classify the information obtained via unconstitutional surveillance and data sharing programs, in addition to the myriad of legal sources. There, FBI personnel will work hard to ensure that nobody who orders pizza at 11:43PM, while purchasing a copy of "Diary of Anne Frank" online, gets away with the undoubtedly terrorist activities they might be planning (they may not even know it themselves, but that's just because the data mining is so good).

The point of data mining is that some connections are not obvious at all, pizza and books are legitimate pieces of data from a scientific/statistical point of view.
We know that the enemy favors couriers, a routine delivery person like a pizza delivery boy makes a good courier. Especially since it is an easily acquired job.
Common books have been used for ciphers for centuries.
The FBI has successfully mapped out organized crime networks through data mining of the most inconsequential and trivial looking information. It is likely that this technique will be successful against other groups as well. You may rightfully question the legality of acquisition methods and raise privacy concerns, but mocking the technique only demonstrates an ignorance of the topic.
We should call them "Departments of Precrime" because essentially, that's what they are.
