Sounds like a crime preventive measure that so far hasn’t had a published cutoff threshold for separating innocent from the real perps. I bet once you are picke up in this archive of “suspicious types” it will probably be permanent. Civil rights lawyers will go wild over this as it hints as a form of a “no fly” list by Homeland Security.

Notice that it is advertised as a “pinpoint” level of accuracy. Thats like a typical PR tag ploy commonly seen in forensic news.
