The Informed Commitment Model: Best practice for journalists engaging with reluctant, vulnerable sou...

<jats:p>Investigative journalism is often said to be based on two pillars of information gathering—documents and sources. Yet while document retrieval and analysis has received much attention in recent years, particularly with the advent of computer-assisted reporting and Freedom of Information legislation, remarkably little attention has been given in the journalistic literature to best practice for developing and maintaining sources, especially vulnerable sources with high-risk information. This study analyses four high-profile examples of New Zealand investigative journalism based on revelation by vulnerable and reluctant sources.
