Your stories remind me of that Bellesiles cat (from Emory U, IIRC) that wrote the now discredited book on the gun history of America. He was eventually taken down (and taken down hard), but it took a lot of work on the part of a handful of persistent historians. A lot of connected historians were reluctant to look into the charges that Bellesiles was at best a fraud, more likely a propagandist. Persistence and the white-hot spotlight of publicity eventually took him down.
If Churchill is bought off the white hot light of publicity will go off. If he's fired, the lawsuit and its accompanying relevations will keep it on CU.
