It is said that everyone has a twin out there.

There was one guy who was incorrectly face recognized not once, but three times. Three times the men in blue incorrectly harassed this guy.

Even DNA and fingerprints are not perfect matches.
Even if the actual technology was anywhere close to what they show on Tel-lie-vision.

This is just the new way of giving a reason to harass and detain someone. Anyone.
