There was a trial in the U.K. a little over a decade ago over whether a certain media mogul was engaging in cartel behaviour - and apart from those parties directly involved in the trial, and a few others such as myself who have come to know about the matter through one of the parties involved, nobody even knows it happened. It was deemed to be in the public interest to try him, but it was also deemed a risk to national security for any part of it to be public. He was evidently acquitted, or perhaps proceedings still drag on, with him wagering on a visit from the reaper before judgement is passed - oh irony.
There was a rather incredible turn of events where one of the parties who had been asked/told to be involved tried to go to the press (not owned by said mogul), and was promptly ratted out to the government, and the prime minister of the day then went on the ten o’clock news to denounce them, bringing their rather comfortable cosy-to-the-establishment life to a crashing end. They became a national hate figure overnight.
Really, we don’t even know what we don’t know — at least in this case we know that antitrust proceedings are underway.
