This technology was first hinted in the 2008 blockbuster movie "The Dark Knight" The government will soon use this technology in every single CCTV camera on the streets. This technology will be used to track persons of interest, criminals, and abducted people. Apple is likely complicit in this as they are acclimating people to accept this technology as non-intrusive to privacy. A friend of mine who works for the department of technology of New York City told me they will be rolling out this technology to all city cameras very soon and that there will be a giant boom in the cyber security field because of it. Also, a lot of police stations, including New York City are now requiring retinal scans of arrested individuals to which people can not decline. This is by no means any sort of conspiracy, it is simply untold reality.
