And so for most of the sort of things that we deal with day to day, it's quite clear what's happening. But there's another range of stories where it's actually a bit more sensitive, I think, for stories like where, potentially, someone's investigating potentially a corrupt official, or those other kind of stories where, basically, journalists, often what they're doing is they're putting together pieces of information from a variety of different sources, and they're trying to corroborate that. And often people will only step forward and disclose information with a clear understanding that they're going to be able to do so anonymously, because often there's a power imbalance and there's a real fear of repercussions. I think many countries, including New Zealand, actually acknowledge and recognise this, and they do afford journalists some particular protections. And I think that's because there's the understanding that many things are in the public interest, but they wouldn't be coming forward and being brought forward to the media unless those protections were available.
