So, interesting concept in the new files.
"Ghosting" (not the social concept).
A person moves through a crowd. As cameras ID his face, they turn away or shut off, sending a signal to other cameras to do the same thing, then erase the footage. Static cameras just shut off and erase footage. People in the vicinity get bot sales calls that distract them for 30 seconds. Wifi objects in the area drop coverage, distracting people. Phone cameras shut off (Apple already has this feature for police). The person walking has been trained in the usual ways of not being noticed (clothing that doesn't stand out, not making eye contact, etc) His Uber is always on time, allowing him to keep moving to wherever he's moving, without standing around. Never has to wait for an elevator, that sort of thing. The chip in his credit card changes the card's unique ID from one valid account to another. OLRs ignore cars he is in, the same way cameras do (deleting memory).
Far more difficult to implement than it sounds, but possible. And I can think of a hundred uses for it.
