I'd like to preface this by saying that I don't consider threats to national security to be something that is a journalistic rights issue.

That said, in this case we haven't had a magistrate order a journalist to reveal who their source was, so journalistic source confidentiality hasn't been breached. Instead we saw a portion of a slow, deliberate and year-long investigation by the federal police with no pressure placed on the journalists themselves - either in the form of arrests or coercion to reveal secrets. So this still wouldn't be a journalistic rights issue.

I think most journalists would argue that they should have the right not to have their email searched by police to discover a source's identity, even if, as a matter of law, they don't.
