Glenn Greenwald's partner, David Miranda, was carrying a piece of paper with a password to access classified documents--posing a threat to national security—senior officials at the High Court in London have determined. They expanded an order permitting Scotland Yard to examine electronic devices seized from Miranda when he was detained at London's Heathrow Airport on August 18. Scotland Yard had already announced the launch of a criminal investigation last week, but a senior Cabinet Office security adviser issued a handwritten statement to the court, Friday, claiming that the seized documents—specifically a piece of paper Miranda had been carrying with a password on it—posed a serious threat to national security. Miranda, Greenwald, and The Guardian showed "very poor judgement," the statement read.
