Another domino falls. John Yates, the deputy commissioner of London’s Metropolitan Police (also known as Scotland Yard), has resigned after facing criticism that he didn’t properly investigate phone-hacking allegations at News of the World. Yates made the call in 2009 not to reopen a probe of Rupert Murdoch’s British tabloid, and his judgment has been called into question lately as new evidence of corruption mounts. Yates has also been called to the House of Commons to “clarify” previous testimony. His resignation follows that of Scotland Yard chief Sir Paul Stephenson, who also quit over his ties to the scandal.
