According to the Guardian (and plenty of other news sources) Murdoch has been tweeting his views on Hubard's scam:
Scientology back in news.Very weird cult, but big, big money involved with Tom Cruise either number two or three in hiearchy. — Rupert Murdoch(@rupertmurdoch)
Watch Katie Holmes and Scientology story develop. Something creepy, maybe even evil, about these people. — Rupert Murdoch(@rupertmurdoch)
Mormons on the other hand are okay (fair enough). "Mormonism a mystery to me, but Mormons certainly not evil."
So a despicable megalomaniac one of whose papers hacked the phone of a dead girl, is going against a lunatic and highly litigious money making cult. May the battle be bloody and both sides lose.
