Yeah, I was aware of these and while it’s pretty crazy, I also used to drive with a radar detector detector detector[1] so it’s not like electronic warfare with the police is an alien concept to me. I just thought Britain was too polite to literally threaten people with SWAT teams over unpaid TV licenses.
[1] A radar detector is used to detect police radars, which are used to catch speeders. Police responded with radar detector detectors, which detect radar detectors, which are legal but police don’t like them. The citizen countermeasure, built into your better radar detectors, is the radar detector detector detector, which detects radar detector detectors and can additionally protect your radar detector from itself being detected. I am not aware of the successful invention of a radar detector detector detector detector.
