       | FTFA: "Data on commercial cameras available at the time suggest

       | 
       | This is so wildly inaccurate that it really makes this whole
       | thing seem highly suspicious.
       | 
       | The average CCTV camera in a municipal deployment, especially
       | ones from several years ago, would be a fixed 1080p camera with
       | an adjustable 4-8mm lens, which is set at a fixed focal point
       | upon installation. In other words, not a PTZ, not a long range
       | lens. The mounting height is usually 10+ feet high, which overall
       | makes it really poor for face recognition purposes.
       | 
       | This is not to say that many of these cameras cannot capture at
       | least _some_ faces with a level of detail that is sufficient for
       | face-rec, but this camera network is nowhere near the ability to
       | track a person /their movements throughout the city.

         | 
         | - Ability to track across multiple cameras exists today (this
