This is more frightening than the implications of the article and all the comments I've seen here so far. To be clear, what you're describing is a system for triggering asynchronous, automated "background checks" (no doubt based on a secret methodology) against Americans, the results of which will then be applied at biometric checkpoints and used to justify taking individuals into custody for "further screening". Do you understand the implications of a government using such a system against its citizens? Do you really think the TSA will effectively prevent other actors from using their database? Even if they do, do you think this model and precedent won't be exploited by other actors? FFS, they're already talking about ripping off the photos we have to have taken for our regular state-issued IDs.
