So now that the "trial" has failed we're going to stop doing face scanning, right? ...right???

  In the UK it has worked at other places
  "He said 103 arrests has been made so far and there was one false alert which did not result in an arrest.
  Supt Luke Dillon said overall crime figures in the Fairfield ward, where the pilot has been held, fell by 12% per cent.
  "We're seeing reductions in almost all crime types, certainly in shoplifting and robbery," he said. "

    Honestly I find the correlations that LFR has worked in other places very weak.
    For example the falling of the crime figures could be just because there where more officers around attending the camera's. Or actually that just there being a camera already has a deterring effect, I assume the perpetrators didn't know it was LFR.
    I also wonder if the resources spend in a traditional way would have been more effective. I think 3 month trail to make 103 arrests seems a bit low, but I am not familiar with the normal "arrest rate" in that area.

    In Croydon shoplifting occurs in many places not covered by these cameras.
    Most shops do have cameras and they do not seem to be a deterrant.
    Also the cameras were not in constant use for 3 months. I don't think we know for how long and when they were actually used.
