Upsampling used to be pitched in papers as a way to add plausible information to images so they don't look so degraded.
Recently, however, there's been a lot of work pitching upsampling for "deblurring" faces, which seems like a great way for LEO to run the programme until they hit on a face that most likely looks like a person of interest.
Hell, you can even make it explicitly so that the net takes two inputs, the blurred image and a suspects image, and generate a plausible upsample that is similar to the suspect.
That sounds like bad faith science that no judge would accept, but perfectly legitimate technologies like DNA testing has historically been abused this way in the courts.
