I wonder how many of their tactics they withheld from the story, given that child abusers will be taking notes. At least there's not much that can be done about location recognition.
- DanBC 10y agoThere were some hints in the article. Forensic teams look at brands. Coca Cola labeling isn't identical across the world, and is very common, so leaving a bottle of coca cola in the room can provide a hint to location. (There was a programme on BBC Radio 4 that mentioned programmers getting together with police to develop machine-recognition of coca cola bottles. Sadly, the BBC search is hopelessly poor, so I'm unable to find the programme.) There's other stuff, like wallpaper patterns and fabric patterns in windows. There's a bunch of image processing, the most obvious example being swirly-face man, but there are plenty of others. https://en.wikipedia.org/wiki/Christopher_Paul_Neil https://en.wikipedia.org/wiki/Christopher_Paul_Neil
