So when a suspicious person comes to the attention of the troops, they get his finger prints, a photo, a record of his voice, and a DNA sample. He may unknowingly get a RFID tag planted on or in him. They ask him who is related to. He may or may not be truthful about that but the wrong answers also give a pattern, there will be a list of names. He’s in the data base now. If he turns up on a camera the computer facial recognition program says “hello!” If he touches anything with bare hands he’ll leave a marker. A war zone dream and a domestic nightmare.
