Opening Session - Why "Investigation is Collaboration"?



11:30 - 12:30 CET

Keynote - Investigation Philosophies


(Article with snapshots from the session)
  • with Crofton Black
Session details:

Do we know things? How do we know them? Philosophers have been asking these questions for thousands of years. But for investigators and researchers, they have a particular resonance. What do we do when we investigate? How do we derive meaning from data and the absence of data? I’m going to look at some investigative practices and reflect on their relation to ancient and modern ideas about the acquisition of knowledge. I’ll talk about my work on extraordinary rendition, outsourced warfare and some other projects.

About the speaker:

Crofton Black is a writer and investigator. He is co-author of Negative Publicity: Artefacts of Extraordinary Rendition and CIA Torture Unredacted, and works on technology and security topics for The Bureau of Investigative Journalism in London. Before this he was a history of philosophy academic, specialising in theories of knowledge and interpretation. He has a PhD from the Warburg Institute, London and was a Humboldt Fellow at the Freie Universität Berlin. More info at https://www.crofton.black/

Keynote - Collaboration Is a Lifesaver. Literally


(Session-based article)
  • with Pavla Holcová, OCCRP
Session details:

Imagine you have the story of your life. Sensitive material, classified documents, exclusive testimonies. You are the one and only journalist doing the story, the one and only who has it all. And you are going to show to all your competitors how powerful a story you can deliver. And this is exactly what makes you an easy target, this is what might get you killed. Ten years ago, collaborative journalism was something unusual, quite often weird – why to share my precious information with someone else? Fortunately, this has changed. Collaborative stories are a new trend, because they are powerful, they have impact and they protect the journalists; because killing one is easy, killing a network is impossible. I will share my personal experience on how this works: how to cooperate, how to share, and how to coordinate such a stories.

About the speaker:

Based in Prague, Pavla Holcová is a regional editor for Central Europe with the Organized Crime and Corruption Reporting Project (OCCRP). She is an investigative journalist and founder of independent investigative center investigace.cz in the Czech Republic. She has contributed to major cross-border projects such as the Panama Papers, the Paradise Papers, the Russian Laundromat, and the Azerbaijani Laundromat. Together with her colleague Ján Kuciak, she exposed ties between the Slovak government and Italian mafia. She has also investigated massive illegal arms sales to Syria during the war, explored links between the global cocaine trade and Balkan organized crime groups, and identified illegal real-estate investments by politicians. In November 2016, Pavla was selected among a hundred New Europe changemakers and a hundred people changing Central and Eastern Europe for the better. In 2018, she was selected for the European Young Leaders initiative.

Artistic Practice and Investigative Research

  • with Heba Y. Amin
Session details:

Artists have always engaged in diverse and creative approaches to research. More recently, however, they have carved critical spaces for urgent political topics that are otherwise difficult, if not dangerous, to confront elsewhere. This talk addresses the potential of framing investigative research within the context of arts and culture for social justice. Through my work, I will discuss the political implications of image production on the Middle East and Africa in the last 150 years and artistic methodologies aimed at making the racially deterministic power dynamics of technology more evident.

16:30 - 17:30 CET

Keynote - Walking in the Sunshine: The joys of transparent investigation

  • with Jim Mintz, DigLab
Session details:

Stepping back from particular cases and contexts, I offer a philosophy of investigation that I find leads to deep investigations and happy investigators: consider gathering the facts openly, if it is safe to do so. Don’t worry about the subjects hearing about your investigation - contact everyone who’s knowledgeable, even those involved in the wrongdoing, human to human. Tell them about the team you work with; express your passion for getting the story right; show your curiosity and humility about what you’re learning. Investigate in the sunshine.

About the Speaker:

Jim Mintz has been digging into wrongdoing for 40 years. He was first a freelance reporter, then became a private investigator and founded MinzGroup and then professor of investigative reporting at Columbia Journalism School’s Stabile Program. His foundation, Dig Lab, is a part of the emerging Seek Initiative that is building a movement of citizen investigators. Jim helped create a game in the public interest (it’s free) called Kleptocrat: How to Hide Dirty Money, which helps people practice ways to recognize and bust corruption and money laundering.

(Session Slides / Article with snapshots from the session)
  • with Jose Miguel Calatayud
Session details:

In an increasingly complex social, political and economic environment, and in times of lurking crises, from Covid-19 to the climate emergency, we need to collaborate if we are to investigate such complex phenomena.

An Investigator’s Introduction to Risk Management


(Session Slides / Session-based article)
  • with Léopold Salzenstein
Session details:

Investigating wrongdoings is a risky business. Unfortunately, individual investigators rarely have the resources and guidance to comprehensively assess and mitigate their risks. This session draws on the expertise of professionals and scholars specialised in societal risks, such as disasters or conflicts. I will provide an introduction to the concept of risk and present a practical method to help individuals or small teams manage the risks of their investigation.

Communicating with a purpose: Investigative Storytelling


(Session Slides / Session-based article)
  • with Nuria Tesón
Session details

Why do we investigate? And what would happen to the evidence we gather, the people that confide it to us, those who trust us with their stories, or the ones who commit wrongdoings if that information never sees the light? Communicating and narrating our investigation is key, it is one of the pillars of our work as investigators. Communication might be a double-blade weapon used to create false narratives and manipulate, but in the hands of the right people, in our hands as investigators, communicating with a purpose is essential to achieve change, raise awareness or bring people together, among other things. Investigative Storytelling can be done in different ways and formats, it can be directed to a 'target audience' or fly away beyond our expectations. In this session I will explore some pathways of investigative storytelling and considerations we should keep in mind before deciding the most fitting style(s) for our investigation.

About the Speaker:

Nuria Tesón is an independent multimedia journalist and writer, co-founder of the MásTesón collective. She is based in the Middle East where she covered the most newsworthy events of the region for the past 12 years. She has investigated among others: the trail of mercenaries in Libya during the war, the activities of fighters being trained by the Libyan militias in the following years as well as the Al Qaeda infiltration in the East of Libya; the connections between terrorist attackers of the March 2004 Madrid train bombings with Spanish foreign fighters in Syria; fracking; political corruption in Spain and Romania; the destruction of native rainforest in Brazil's Amazon basin and its impact on the local communities. Her work has been featured in Time, CNN, Al Jazeera, AJ+, The New York Times, France 24, El País, and Le Monde among others, and exhibited on several continents. She collaborates with universities, institutions and private entities creating content for seminars, workshops, exhibitions and performances around journalism, conflict zone coverage, the use of Art and Journalism to achieve structural changes, media and conflict, coverages with a gender perspective.

Keynote - Mnemonic: Supporting justice and accountability through effective digital documentation of human rights violations


(Session-based article)
  • with Jeff Deutch, Mnemonic / Syrian Archive

Session details:

In 2014 the Syrian Archive was established as a rapid response project working in close collaboration with Syrian reporters and documentation groups to preserve digital information of the Syrian conflict: images, videos, and other postings that are invaluable historical artifacts and potential evidence of human rights abuses. Mnemonic grew out of the recognition that Syrian Archive’s workflows could be adapted to other locations where human rights violations must be documented and preserved but the ecosystems to do so are underdeveloped. Since 2017, Mnemonic has used our position as a cross-sectoral, cross-disciplinary organisation to provide the tools and methodologies that enable human rights defenders to use digital information in the fight for justice and demand accountability. In this talk, I will share some of our methodologies, discuss some of the ways in which we have collaborated with others, and share some of the key considerations we have had to navigate within the human rights investigative space.

About the speaker:

Jeff Deutch is director of operations and research at Mnemonic and co-founder of Syrian Archive. With more than 10 years of experience in the human rights and nonprofit sector, Jeff previously worked with Tactical Tech where he engaged in research concerning the risk and barriers activist communities face in using technology for transparency and accountability. Jeff has a doctorate from Humboldt University in Berlin, Masters in Public Policy from Hertie School of Governance, and a Bachelor of Arts from Hampshire College. He is also a fellow and member of the steering committee at the Centre for Internet and Human Rights.

About the Conference and its Organisers

"Investigation is Collaboration" was a conference that brought together the stories of investigators, investigative initiatives and techniques that have emerged and developed lately, in the hope of getting individuals interested in delving deeper into topics and questions, to get inspired and learn from these techniques and stories.

This event was organised and hosted by Exposing the Invisible - ETI - a Tactical Tech project that has been actively experimenting with ways to promote investigation as one of the most important forms of public engagement. Through a series of films, interviews, guides and resources, ETI looks at different techniques, tools and methods along with the individual practices of those working at the new frontiers of investigation. ETI's flagship project is the Exposing the Invisible Kit, a collaborative, self-learning resource that makes investigative techniques and tools used by experienced investigators more accessible to people and communities who feel motivated to start their own investigations, without losing sight of ethical or safety considerations.

Tactical Tech is an international NGO that engages with citizens and civil-society organisations to explore and mitigate the impacts of technology on society.

The conference was part of a one-year EU-funded project developed by Tactical Tech, which focused on organising activities and developing self-learning resources for journalists, citizen investigators, activists, researchers and others interested to receive training in safe online and offline investigative techniques.
