Leveson: Murdoch hints that hacking crisis could spread to US In his witness statement, Mr Murdoch gives details of the working of News International's Management and Standards Committee, which was set up partly to provide police with any relevant evidence of phone-hacking. He says: "Since July 2011, the MSC, working with a legal team, has actively cooperated with the Metropolitan Police as well as with the United States Department of Justice, turning over evidence of alleged or suspected illegality, and responding to all requests for information. This has led to the arrests of a number of NI employees. Our cooperation is continuing to date. Mr Murdoch repeats his comment, made to the Parliamentary culture, media and sport select committee last year, that he had been "humbled by the events of the past year" and "with the wisdom of hindsight, I have learned that even experienced and long serving members of staff can fail to meet their responsibilities." He adds: "All of us regret that some of our colleagues fell far short of what is expected of them. I feel great personal regret that we did not respond more quickly or effectively. This company has been my life's work, and I feel a strong sense of responsibility for everything we do and fail to do.
