This is a big week for Rupert and James Murdoch. The father and son face more questions from a wide-ranging judicial investigation into press abuses at British units of News Corporation: tabloid phone hacking, computer hacking and a police bribery scandal. Monday marked yet another embarrassing day for News Corp and the Murdochs as Sky News acknowledged it had hacked into the email of the target of two stories, despite explicitly telling the inquiry in September it had not been involved in any hacking.
