July 8, 2008: The U.S. has revealed that many terrorists it arrests, or kills, in Iraq, Afghanistan and elsewhere around the world, already have arrest records in the United States and other nations. They know this because early on in the war on terror, the Department of Defense adopted many practices that major police departments have long taken for granted. One of the more useful techniques is biometrics. That is, every time the troops encounter a "person of interest", they don't just take their name and address, they also use portable electronic tools to take fingerprints, a retinal scan and photos. All this is stored in a database, which now contains hundreds of thousands of records for Iraqis, Afghans, and other "persons of interest". The fingerprints are particularly useful, because when they are stored electronically, you can search and find out immediately if the print you have just lifted from somewhere else, like the fragment of a car bomb, is in there or not. The digital photos, from several angles, are also useful, because these pictures are run through software that creates a numeric ID that can be used by security cameras to look for some one specific, or for finding someone from a witness description. Other nations are digitizing their mug shots, and this enables these people to be quickly checked against those in the American database.

For decades, the U.S. military has regularly collected huge amounts of information from accidents, or even combat encounters. So now, it's no surprise that forensics teams examine each bombing (car or roadside), to see if they can get fingerprints. Often bomb makers are found this way, because raids frequently encounter suspicious characters, but no evidence to justify arresting them. It only takes about two minutes per subject to take the biometric data, so any suspicious characters are added to the database. Now, after several years of this, raiding parties know to grab any guy who seems to panic at the sight of the biometrics equipment coming out. The terrorists know that biometrics is bad news for them, and they fear it.

Naturally, the FBI and U.S. intelligence agencies were data mining this database, and running cross checks with other databases of people with known, or suspected, criminal backgrounds. As was long suspected, many Islamic terrorists had spent time in Western nations, where they participated in criminal scams, and were often arrested. Same pattern in Moslem nations, where there was a strong linkage between criminal behavior in general, and association with Islamic terrorist organizations. Some of this is because the same kind of personality is attracted to both lifestyles, but it's also long been a common practice for Islamic terrorists to raise money, and gain access to weapons and explosives, via criminal activities and connections with other criminals.

Pro-terrorist message boards on the Internet have long been discussing the biometrics, and the likelihood that the Western intelligence agencies were tracking terrorists with this kind of information. This is probably why the FBI is going public with this program. They discovered early on in Afghanistan, for example, that about one percent of the al Qaeda suspects they picked up, already had an arrest record back in the United States.
