I scanned a screw that holds microphones and low resolution infrared cameras into my office’s wall. These devices were installed in my department’s offices, often without asking for consent of the occupants. I removed the whole sensor at one point, but got in a lot of trouble. Instead, this time I removed a screw and scanned that. The screw is unique, so this is “evidence” of my “crime”, in that it is evidence that this specific screw was removed from my office wall, and put into a fairly rare kind of microscope.
