In this special edition for the 4th CIJ Logan Symposium Collective Intelligence, Disruption Network Lab holds a panel discussion on how open-source intelligence tools and collective strategies reconfigure investigations. Moderated by Tatiana Bazzichelli, this talk brings together investigative television journalist Natalie Sedletska, software artisan and ethical hacker Denis “Jaromil” Roio, and data team lead at OCCRP Friedrich Lindenberg. This panel focuses on the one hand on methods of making leaks and large datasets accessible to a wider public, on the other hand on models to avoid the exploitation of sensitive data by authorities or organised crime.

Natalie Sedletska shares the experience of the YanukovychLeaks National Project, concerning the nearly 200 folders of documents found in the lake at the residence of former president of Ukraine, thrown to destroy them as people were escaping the luxury residence. The documents were rescued by volunteer divers and systematised, investigated and published by a group of journalists and activists to make them available to citizens around the world.

Denis “Jaromil” Roio speaks about the importance of social movements challenging city policy on money speculation and hidden illicit cash flows, finding ways to have agency through collectivising big data controlled by financial and institutional powers.

Friedrich Lindenberg presents some of the recent work OCCRP’s data team has done analysing a large-scale dataset related to the murder investigation of Slovak journalist Jan Kuciak. He also summarises some lessons learned about the use of data in investigative reporting, and the limitations of transparency as a method and an ideal, contributing another perspective coming from the context of investigating organised crime and corruption.
