I've heard most of the R4 reports when originally broadcast and again currently. I haven't heard any racial slur.
In the 1984 novel justice was seen to be done as long as someone paid, maybe not the culprit. One day a robot may knock on my door and shoot me. Might be the wrong door, duff gps or whatever but trust in technology will have become the norm and it will be nobody's fault.
I note that the car park number recognition scam is not unique, actual story in the post above is not the one that resulted in summons in news.
