Danbury and Townend explore the practical implications of technological advances and legal structures on the assumption that “journalists should protect a source…whatever the personal and organisational cost.” They conclude that at the individual level, ethical codes should require journalists to warn sources of vulnerabilities before offering assurances of anonymity, while organisations should train journalists on how to have these conversations.
