Reporting a story requires detail. But how much is enough? Or too much?

Revisiting some of the most difficult stories he and other journalists have had to report, BBC International Editor Jeremy Bowen looks at some of the obstacles that stand between journalists and what Watergate reporter Carl Bernstein once called the ‘best obtainable version of the truth’.

Jeremy speaks with: Andrew Norfolk - chief investigative reporter for The Times, Aisha K. Gill - Professor of Criminology at University of Bristol’s Centre for Gender and Violence Research, Andrew Mosley - editor of Rotherham Advertiser, Emily Bell - Professor at Columbia University Journalism School and Eliot Higgins - founder of investigative journalism group Bellingcat.
