Not just a terrorist score, a criminal score

In all the excitement about DHS's ATS program and "terrorist scores", one of the things that's getting missed is that the system isn't just being used to look for terrorists, but also "criminals":
The Homeland Security Department called the program "one of the most advanced targeting systems in the world" and said the nation's ability to spot criminals and other security threats "would be critically impaired without access to this data."

It's also been in use since the 1990s:

Ahern declined to disclose any of the rules, but a Homeland Security document on data-mining gave this innocuous example of a risk assessment rule: "If an individual sponsors more than one fiancee for immigration at the same time, there is likelihood of immigration fraud."

Ahern said ATS was first used to rate the risk posed by travelers in the late 1990s, using personal information about them voluntarily supplied by air and cruise lines.

I totally agree that stopping immigration fraud justifies the government knowing what I had for lunch on my last flight to Canada. Don't you? Of course, what's especially telling about this example is that duplicate fiancee visas are something that CIS can easily detect via ordinary records searches (i.e., look for duplicate applications under the same SSN) without any kind of fancy data mining.
