What's changed since Edward Snowden's whistleblowing?

Within a few days, the source of the documents, Edward Snowden, unmasked himself on the Guardian website and for weeks thereafter the stories dominated the news around the world. It has since been memorialised in at least three films, stage dramas, books, numerous academic papers … and even an album.

It led to multiple court actions in which governments were found to have been in breach of their constitutional and/or legal obligations. It led to a scramble by governments to retrospectively pass legislation sanctioning the activities they had been covertly undertaking. And it has led to a number of stable-door attempts to make sure journalists could never again do what the Guardian and others did 10 years ago.

Even now the British government, in hastily revising the laws around official secrecy, is trying to ensure that any editor who behaved as I did 10 years ago would face up to 14 years in prison. Lamentably, the Labour party is not joining a cross-party coalition that would allow whistleblowers and journalists the right to mount a public interest defence.
