• Sommario/riassunto: More journalists are being killed, attacked and intimidated than at any ; time in history.Reporting Dangerously: Journalist Killings, Intimidation and Security examines the statistics and looks at the trends in journalist killings and intimidation around the world. It identifies what factors have led to this rise and positions these in historical and global contexts. This important study also provides case studies and first-hand accounts from journalists working in some of the most dangerous places in the world today and seeks to understand the different pressures they must confront. It also examines industry and political responses to these trends and pressures as well as the latest international initiatives aimed at challenging cultures of impunity and keeping journalists safe. Throughout, the authors argue that journalism contributes a vital if often neglected role in the formation and conduct of civil societies. This is why reporting from ‘uncivil’ places matters and thisis why journalists are often positioned in harm’s way. The responsibility to report in a globalizing world of crises and human insecurity, and the responsibility to try and keep journalists safe while they do so, it is argued, belongs to us all.
