About this whole Damian Green business, although it was clearly ludicrous and thuggish to arrest him for doing what shadow ministers have always done, it doesn't mean that what he was doing was proper. Some of the leaks that he received were legitimate matters of public interest, such as the illegal immigrants working at the Home Office but some were not, such as the list of Labour MPs who were going to rebel over the issues of 42 days detention.
It isn't unreasonable for ministers to have an expectation that they are able to discuss matters in private with civil servants without their deliberations being sent straight to the opposition. It should not be a criminal matter, so the arrests are the most important part of story. It's as if the police started arresting footballers who dive, on suspicion of fraud, it would clearly be an abuse of power but it wouldn't make divers heroes.
Even John le Carré would have difficulty telling this tale
